TrueLoad gives electricians and heat pump installers a fast, defensible way to document existing service capacity — without a load calculation from scratch.
NEC 220.87 lets you use actual measured demand data to prove the existing service is adequate. The problem is — until now — documenting it has been a manual, time-consuming process.
AHJs increasingly require a formal calculation before approving heat pump or EV charger installations on existing services. A verbal assurance isn't enough.
Recommending a service upgrade when one isn't needed adds thousands in cost and weeks of delay — and can kill a sale before it starts.
The code provision exists, but applying it requires AMI data from the utility and a calculation most contractors don't have a tool for. TrueLoad closes that gap.
TrueLoad walks you through the entire NEC 220.87 process — from requesting utility data to printing a report ready for the AHJ.
TrueLoad provides a pre-written email template your customer sends to the utility. The utility sends the interval data file directly to you.
One project per job site. Enter the customer information, your preparer details, and the existing service specifications.
Main breaker size and service voltage. TrueLoad uses these to determine total service capacity in kVA.
List each piece of new equipment — heat pump, EV charger, water heater — and mark whether it's concurrent with the measured peak.
Drag and drop the file from the utility — CSV, Excel, or XML. TrueLoad processes it automatically and identifies the peak demand.
PASS or FAIL is displayed immediately. Print a formatted report ready for permit submission directly from the browser.
TrueLoad is designed for licensed electricians and heat pump installers who need to document service adequacy quickly — not engineers running full Article 220 load calculations.
If you're adding a heat pump, EV charger, or other major load to an existing residential service and want to avoid an unnecessary service upgrade, this is the tool.
TrueLoad is free to use during the current beta period. Sign up, create a project, and have a report ready for the AHJ in under an hour.
