For Food Truck Builders & Fabricators | FTB

For builders & fabricators

A quiet note for the people who build the trucks we calculate for.

If you build food trucks, trailers, or carts for a living, you already know the electrical conversation is one of the messier parts of a build. The customer wants "enough battery." You need a real spec to wire to. The honest answer takes 30 minutes with a spreadsheet you'd rather not be opening at 9 p.m.

That's what this calculator is for — and you're welcome to use it the same way your customers do.

How builders use it

What this isn't

We don't sell installs. We don't refer leads. We don't run a builder directory. We're not trying to insert ourselves between you and your customer — your relationship with them is the build, and that's where the value is. The calculator just makes the electrical conversation faster.

If you want to talk

We're not running a partner program. We're not sending a sales rep. But if you run a build shop and you've spotted something in the calculator that's off for your kind of work — a niche piece of equipment we got wrong, a regional code we missed, a duty cycle that doesn't match what you see on a finished truck — that's the conversation we actually want.

If the math on this site helps your customer ask better electrical questions, the build goes smoother. That's the whole pitch.

A short read for builders

If you've got five minutes: Why food truck builders should size electrical with their customers, not for them — how we think about the handoff, and where most disputes between builders and customers actually start. For the full operator picture — real costs, generator replacement rules, and sizing — point customers to the battery-powered food truck guide.
