VOLTS is a field-ready electrical reference suite built for electricians, apprentices, contractors, technicians, engineers, and serious DIY users.

Get fast access to essential electrical calculators, NEC-oriented references, code books, saved calculations, and practical field tools in one modern app. Core calculators work offline, so you can keep working where signal is limited.

ELECTRICAL CALCULATORS

• Conduit Fill
Calculate allowable conduit fill for common raceways using conductor size, type, and quantity.

• Wire Derating
Apply ambient-temperature correction and conductor-bundling adjustments to estimate adjusted ampacity.

• Ampacity Lookup
Review common conductor ampacity values by material, insulation rating, and temperature rating.

• Copper and Aluminum Conversion
Compare common copper and aluminum conductor arrangements for equivalent applications.

• Trade Calc
Calculate voltage, current, power, and resistance using common electrical formulas.

• Voltage Drop
Estimate voltage loss, percentage drop, and delivered voltage for common circuit conditions.

REFERENCE AND FIELD TOOLS

• Knowledge Base
Browse practical electrical references, code-book resources, and trade Q&A.

• In-App PDF Viewer
Open supported electrical reference documents without leaving VOLTS.

• Offline Downloads
Download supported code books and reference PDFs for access when an internet connection is unavailable.

• Saved Calculations
Store frequently used calculations and job references for quick access later.

• Custom Defaults
Set your NEC year, conductor material, insulation rating, temperature unit, raceway, and wire type so calculators are ready to use faster.

BUILT FOR THE FIELD

VOLTS features a clean Electric Glass interface, dark-mode-first design, readable results, fast navigation, haptic feedback, and controls designed for quick use on the job site.

No account is required for standard calculator use. Preferences, saved calculations, and downloaded documents are stored locally on your device.

IMPORTANT NOTICE

VOLTS is an independent calculation and reference tool. It is not affiliated with or endorsed by NFPA. Always verify final work against the adopted code edition, local amendments, project documents, manufacturer instructions, and the Authority Having Jurisdiction.
