Welcome to VoltSpec
VoltSpec is a job specification and estimating platform built for electrical contractors, estimators, and skilled tradespeople. Pick a job type, enter your parameters, and VoltSpec generates a complete, code-compliant Bill of Materials with real part numbers — ready to send to your supply house or export as a professional PDF.
Who it's for: Electrical and skilled trade contractors, estimators, project managers, and supply house sales teams.
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.

Quick Lists
Quick Lists are pre-built templates for common jobs. Instead of configuring every parameter from scratch, pick a template and generate a BOM instantly.
3.1 Browsing Quick Lists
- Open Quick Lists from the Widget Field.
- Browse 32 templates organized by category.
- Use category chips to filter (Residential, Commercial, Industrial, etc.).
- Star your favorites — they appear in a dedicated Favorites section at the top.
3.2 Generating from a Quick List
- Find the template that matches your job.
- Click the template card.
- Review the pre-filled parameters — adjust anything that doesn't match.
- Select your jurisdiction.
- Click Generate — your BOM builds from the template.
3.3 When to Use Quick Lists vs. Full Job Builder
| Use Quick Lists when... | Use Full Builder when... |
|---|---|
| Job matches a common template | Custom or unusual configuration |
| You need to spec fast | Full control over every parameter |
| Repeat work (same job type, same city) | First time with a new job type |
| Training new team members | Complex multi-phase projects |
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
- Click New Job or select from the sidebar.
- Trade selection: Choose your trade. Electrical has 74 job types; other trades have 4–12 each.
- Job type: Pick from the dropdown. Search to filter — typing "panel" shows all panel-related jobs.
- Jurisdiction: Select city and state. VoltSpec auto-applies the correct NEC version, utility requirements, panel series, and device preferences.
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)
4.3 Full Material List vs. Phased View
Click Generate and VoltSpec builds your BOM. View it two ways:
Use the Material View Toggle at the top of the materials section to switch. Your preference is saved automatically.
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.
- Scan the list — anything missing for your specific job?
- Adjust quantities — click any quantity to edit directly.
- Remove items you don't need.
- Add items manually if something's missing.
- Check part numbers — verify against your preferred supplier's catalog.
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
- Open AI Plan Takeoff from the Widget Field.
- Upload your plans — PDF or image files of construction drawings.
- Click Analyze — VoltSpec's AI reads the plans and identifies electrical elements.
- The AI generates a draft material takeoff.
- Review the results — the takeoff appears as an editable draft.
- Accept, edit, or reject individual line items.
- Click Generate BOM to create a full material list from accepted items.
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
- Upload clean, high-resolution plans. Blurry scans produce worse results.
- Use PDF format when possible — preserves scale and text.
- Upload electrical sheets specifically — not the full plan set.
- Review every line item. Don't blindly accept the takeoff.
- Cross-reference with the spec book for manufacturer requirements.
- Start with smaller plans to learn the workflow.

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.
9.2 QuickBooks Online Integration
Setup: Settings → QuickBooks → Connect → Authorize via OAuth2 (secure, VoltSpec never sees your QB password).
| Data | Direction | Notes |
|---|---|---|
| Invoices | VoltSpec → QB | Create/update in QuickBooks |
| Payments | QB → VoltSpec | Status syncs back |
| Customers | Two-way | New customers sync both directions |
| Payroll | VoltSpec → QB | Time entries export to QB payroll |
Conflicts are detected automatically — you choose which version to keep.
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 Version | States |
|---|---|
| NEC 2023 | TX, OK, CO, FL, LA, NM, SC, TN, AZ |
| NEC 2020 | AR, GA, MO, NC |
| NEC 2008 | KS |
Coming soon: Texas adopting NEC 2026 effective September 1, 2026.
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
