Electrical for food truck

Hello,

I would appreciate any input on which type of breaker panel, Romex and number of breakers I would need for the following setup.

I have a concession trailer which will have 2 110V under counter refrigerators, a 110V exhaust fan, fluorescent ceiling lights and several wall outlets which will be used for small counter top appliances.

Any input is appreciated.

Thanks.

Standard voltage is 120v not 110v. Is this going to be shore powered or generator powered?

Sorry, yes 120. Powered by a 3000watt generator.

Is the generator 120v only or is it 240/120v. Have you added up the full load amps of everything that will be on? Seems might be too small a generator, especially if there is any motor driven equipment such as refrigerators.

I'd at least suggest a setup for a 240 generator so generators could easily be swapped out for a larger one. That wouldn't be the case because of special wiring required for a 120 only generator.

You can probably use a 4-space 60 amp main lug panel. It will be intended for 240 volts so the black of the supply cable will need to be pigtailed to both buses. You will need to buy and add a ground bar to the panel.

The cheapest/simplest way to do this is run 3-wire #10 service cord with a NEMA L5-30 twist lock plug from the panel to your generator..

You could also use a prefab 30A power distribution unit like the kind used with generators on a construction site. They have built-in breakers and GFCI protection for added safety in the portable environment.
