Safety & Compliance Disclaimer

VoltSpec is a specification and estimating tool — not a substitute for professional judgment.

You are responsible for verifying all materials, quantities, and code compliance for your specific project. Always confirm requirements with your local Authority Having Jurisdiction (AHJ) before purchasing or installing.

NEC code versions are mapped by jurisdiction, but local amendments, utility requirements, and AHJ interpretations vary. When in doubt, check with your inspector.

Wire and conduit sizing should always be verified against actual field conditions, ambient temperatures, and derating factors.

VoltSpec helps you spec faster and more accurately. The licensed professional on the job is always the final authority.

📸 New Job creation flow
If you do the same type of work regularly, check out Quick Lists (Section 3) — generate BOMs from pre-built templates in one click.

2.2 Navigating the Widget Field

The Widget Field is your workspace — the central hub for all of VoltSpec's tools. It's organized into 3 categories with uniform cards and icons for quick scanning.

Category 1 — Job Tools
Core workflow: job creation, BOM generation, Quick Lists, AI Plan Takeoff.
Category 2 — Project Management
Business ops: labor estimating, scheduling, invoicing, change orders, job costing, field tracking.
Category 3 — Resources & Settings
Submittals, analytics, inventory/tools, team collaboration, trade preferences, account settings.
📸 Widget Field — 3 categories view
On mobile, the Widget Field scrolls vertically. Cards are touch-optimized with 44px minimum tap targets.

2.3 Using the Job Type Sidebar

  1. Category chips across the top filter by trade or specialty (Industrial, HazLoc, Tesla).
  2. Recent jobs appear at the top for quick repeat access.
  3. Search/filter narrows the full 134 job types as you type.
  4. Dropdown opens downward on mobile so it doesn't clip.
📸 Job Type Sidebar with category chips
The sidebar remembers your recent jobs across sessions. Your top 5–6 job types will always be right at the top.

2.4 Trial Code Redemption & Pro Features

Building a Job

This is the heart of VoltSpec — the full workflow from job selection to finished BOM.

4.1 Selecting Job Type and Jurisdiction

  1. Click New Job or select from the sidebar.
  2. Trade selection: Choose your trade. Electrical has 74 job types; other trades have 4–12 each.
  3. Job type: Pick from the dropdown. Search to filter — typing "panel" shows all panel-related jobs.
  4. Jurisdiction: Select city and state. VoltSpec auto-applies the correct NEC version, utility requirements, panel series, and device preferences.
📸 Job type dropdown with search filter
VoltSpec applies the NEC version adopted by your state. Local amendments and AHJ interpretations may differ. Always verify with your inspector for the specific project address.

4.2 Entering Job Parameters

After selecting your job type and jurisdiction, you'll see fields specific to that job type. Common parameters include:

  • Panel size (100A, 200A, 400A, etc.)
  • Number of circuits / spaces
  • Wire run lengths (feet)
  • Conduit type (EMT, PVC, rigid, flex)
  • Service type (overhead, underground)
  • Special requirements (GFCI, AFCI, surge protection, whole-house generator)
📸 Job parameter entry form
Don't overthink the parameters. Enter what you know — VoltSpec uses sensible defaults for anything left blank. You can always edit the BOM after generation.

4.3 Full Material List vs. Phased View

Click Generate and VoltSpec builds your BOM. View it two ways:

Full Material List (Default)
Every item in one list. Best for simple jobs, quick ordering, and sending a complete list to your supply house.
Phased View
Materials grouped by construction phase. Best for staged construction, phase-based ordering, and multi-crew coordination.

Use the Material View Toggle at the top of the materials section to switch. Your preference is saved automatically.

📸 Material View Toggle — Full List and Phased View
Start with Phased View on larger jobs. Order materials in stages so you're not sitting on $10K of trim material during rough-in.

4.4 Understanding Phases

In Phased View, materials are grouped into construction phases typical for the job type:

  • Rough-In — boxes, conduit, wire, mounting hardware
  • Trim-Out — devices, covers, fixtures
  • Final — panels, breakers, labeling, testing equipment
  • Service — meter base, service entrance, utility coordination items

Phases vary by job type. The Phase Selector lets you view one phase at a time or all together.

4.5 Reviewing and Editing the Material List

Your generated BOM is a starting point — always review it.

  1. Scan the list — anything missing for your specific job?
  2. Adjust quantities — click any quantity to edit directly.
  3. Remove items you don't need.
  4. Add items manually if something's missing.
  5. Check part numbers — verify against your preferred supplier's catalog.
📸 BOM with editable quantities
VoltSpec generates material lists based on standard configurations. Unusual site conditions, derating requirements, or local amendments may require additional or different materials. Always verify your BOM against actual job conditions.

Pricing notes: Most items show public reference pricing as a baseline estimate. Wire and conduit always show "Speak to sales" — commodity pricing changes too frequently for automation. Call your supply house for current pricing.

AI Plan Takeoff

AI Plan Takeoff analyzes uploaded construction blueprints and extracts material requirements automatically. It turns hours of manual plan reading into a starting point you can refine in minutes.

5.1 How It Works

  1. Open AI Plan Takeoff from the Widget Field.
  2. Upload your plans — PDF or image files of construction drawings.
  3. Click Analyze — VoltSpec's AI reads the plans and identifies electrical elements.
  4. The AI generates a draft material takeoff.
  5. Review the results — the takeoff appears as an editable draft.
  6. Accept, edit, or reject individual line items.
  7. Click Generate BOM to create a full material list from accepted items.
📸 AI Plan Takeoff — upload and results

5.2 What AI Does and Doesn't Do

What it does:

  • Identifies panel schedules, circuit layouts, and device symbols
  • Extracts quantities and types of fixtures, devices, and equipment
  • Recognizes standard electrical symbols
  • Maps items to VoltSpec's catalog of real part numbers

What it does NOT do:

  • Guarantee accuracy — it's a starting point, not gospel
  • Replace a qualified estimator — complex plans reduce accuracy
  • Read specifications — spec'd manufacturers need manual verification
  • Calculate wire runs — lengths need field verification
  • Interpret local code amendments — jurisdiction rules applied separately

5.3 Best Practices for Accuracy

  1. Upload clean, high-resolution plans. Blurry scans produce worse results.
  2. Use PDF format when possible — preserves scale and text.
  3. Upload electrical sheets specifically — not the full plan set.
  4. Review every line item. Don't blindly accept the takeoff.
  5. Cross-reference with the spec book for manufacturer requirements.
  6. Start with smaller plans to learn the workflow.
AI Plan Takeoff is an estimating aid. The AI may miss items, miscalculate quantities, or misidentify materials. The contractor or estimator reviewing the takeoff is responsible for the final material list. Never order directly from an unreviewed AI takeoff.
Use AI Takeoff to get 80% of the way there fast, then spend your time on the 20% that requires human expertise — site-specific conditions, spec compliance, and coordination items.

Tools & Features

6.1 Panel Schedule / SVG Blueprint

Generate a visual panel schedule showing breaker layout, circuit assignments, and load calculations.

  1. Open Panel Schedule from the Widget Field.

  2. Select the job — auto-fills from BOM and labor estimates.
  3. Customize scope, investment summary, payment terms, T&C.
  4. Export to PDF — customer-facing proposal with signature lines.
Save your company info and standard terms once — they carry forward to every invoice and proposal.

6.5 Job Costing

Track estimated vs. actual costs to understand profitability.

  1. Open Job Costing and select a job.
  2. View: Estimated (from BOM + labor) vs. Actual (invoices, time, purchases) vs. Variance (under / over budget).
  3. Drill into categories: materials, labor, overhead, subcontractors.
  4. Export to PDF with variance analysis.
Review job costing after every completed job. Over time, you'll see which job types you bid well and which run over. That's how you sharpen estimates.

6.6 Field Time Tracking & Service

Time Tracking:

  1. Clock in when starting — captures time and location.
  2. Clock out when done.
  3. VoltSpec auto-detects premiums (overtime, holiday, hazard).
  4. View weekly timesheets per crew member.
  5. Export payroll CSV — ready for your payroll system.

Field Service:

  • GPS geofencing — verify crew is at the correct site
  • Photo documentation — capture conditions and progress
  • Digital signatures — get sign-offs in the field
  • Daily reports — auto-generated from time entries + notes
  • Texas heat safety — alerts per OSHA guidelines
Heat safety features are informational aids based on OSHA guidelines. They do not replace your company's heat illness prevention program. Follow your employer's safety protocols.

6.7 Scheduling

  1. Open Scheduling.
  2. Calendar view — all jobs and assignments.
  3. Gantt chart — project timelines with dependencies.
  4. Crew roster — assign members to jobs and shifts.
  5. VoltSpec detects double-booking, overtime risk, and scheduling conflicts.
  6. Shutdown templates — for planned outage work.
  7. LOTO tracking — Lock Out/Tag Out scheduling.
LOTO procedures in VoltSpec are scheduling and tracking aids. They do not replace your company's LOTO program, lockout devices, or verification procedures required by OSHA 29 CFR 1910.147.

6.8 Inventory & Tools

  • Material tracking: Allocate to jobs, track on-site vs. in-shop, low-stock alerts with reorder suggestions.
  • Tool tracking: Checkout/checkin, calibration tracking with expiry warnings, job-based assignment.
Set up calibration tracking for your test equipment. An out-of-cal meter on inspection day is an expensive mistake.

6.9 Analytics Dashboard

Advanced Topics

9.1 Offline Mode

VoltSpec works without internet — critical for job sites with poor connectivity.

How it works:

  • When online, VoltSpec caches job data locally (IndexedDB).
  • Offline, you can view/edit jobs, create time entries, review material lists, access cached pricing.
  • When connectivity returns, VoltSpec syncs automatically in the background.
  • A connectivity indicator shows your current status.

Limitations:

  • AI Plan Takeoff requires internet.
  • New BOM generation may be limited (depends on cached catalog).
  • Real-time collaboration requires connectivity.
Before heading to a site with poor connectivity, open the jobs you'll need while on Wi-Fi to cache data locally.

9.2 QuickBooks Online Integration

Setup: Settings → QuickBooks → Connect → Authorize via OAuth2 (secure, VoltSpec never sees your QB password).

DataDirectionNotes
InvoicesVoltSpec → QBCreate/update in QuickBooks
PaymentsQB → VoltSpecStatus syncs back
CustomersTwo-wayNew customers sync both directions
PayrollVoltSpec → QBTime entries export to QB payroll

Conflicts are detected automatically — you choose which version to keep.

Set up QuickBooks sync early. Retroactively importing months of invoices is painful.

9.3 Pricing Notes

  • VoltSpec shows public reference pricing — a baseline for estimating, not a quote.
  • Your actual pricing depends on your supply house relationship, contracts, and volume.
  • Wire and conduit always show "Speak to sales." Commodity prices change daily — any automated price would be wrong by the time you order.
  • For accurate costing, get a formal quote from your preferred distributor.

9.4 Jurisdiction & NEC Code Handling

VoltSpec maps every jurisdiction to an NEC version, utility requirements, panel series, and device preferences — all applied automatically when you select a city/state.

NEC VersionStates
NEC 2023TX, OK, CO, FL, LA, NM, SC, TN, AZ
NEC 2020AR, GA, MO, NC
NEC 2008KS

Coming soon: Texas adopting NEC 2026 effective September 1, 2026.

VoltSpec applies the state-level NEC version. Local jurisdictions may adopt different versions or have amendments. Your AHJ has the final say. Always confirm the applicable code version with your local building department.

9.5 Industrial & HazLoc Jobs

Industrial: 19 specialized job types for higher voltages, larger equipment, and stricter safety protocols.

HazLoc: 8 job types for Class I/II/III, Division 1/2 hazardous locations per NEC Article 500:

  • Dedicated material catalog with explosion-proof and intrinsically safe alternatives
  • Recommendation engine based on classification
  • Automatic HazLoc flagging on change orders
  • Mandatory sign-off — cannot be bypassed
  • HazLoc labor premiums auto-calculated
  • Industrial onboarding flow for first-time users
Hazardous Location classification must be performed by qualified personnel per NEC Article 500 and OSHA standards. VoltSpec assists with material selection after classification — it does not perform the classification itself. Improper HazLoc material selection can result in explosions, fires, and loss of life. Take this seriously.

Troubleshooting & Support

10.1 Common Issues

BOM won't generate
Check your jurisdiction (85 supported), required fields (highlighted red), and try refreshing.
PDF won't download
Use a modern browser (Chrome, Firefox, Edge, Safari). On mobile, check your Downloads folder. Allow pop-ups for voltspec.online.
Pricing shows "Speak to sales"
Intentional for wire and conduit. Commodity pricing changes too frequently. Contact your supply house.
Offline mode not working
First visit must be online (to cache data). Cache clears reset offline data. Private/incognito doesn't support offline.
QuickBooks sync issues
Re-authenticate (tokens expire) via Settings → QuickBooks. Check conflict log for unresolved conflicts.
Trial code not working
Check for extra spaces. Each code is single-use per account. Codes have expiration dates.
