Homemade concession help please

I am, after a lot of restoration, etc.ready to wire my mobile concession unit, a 65 28 ft. Airstream. It will have a espresso maker and all the stuff with that (110), a sandwich prep reach in, a freezer, another fridge probably, and a few other electrical appliances that won't run constantly, like a small on demand hot water, coffee maker, sandwich press, etc (all 110). How many amps do I need, what shore line do I need, etc? Help me with the formula, you seasoned concession guys!
Any assistance appreciated.
Thanks.

if you are running everything with electricity,,,you are going to need at least a min. of 30 amps....and even more important, is that you will need to check and see if the location can provide the necessary power.

you can figure out your amp requirement by dividing watts by volts to get the amp requirement.

i get my power for my trailer from the city, and i have to use 3 seperate 20amp plugs to run my business.
i have a fridge, micro , grill, steamer , a burner for hot dogs , water pump, water heater and flor. lights.
hope this helps

Add up every single thing that is electrical in the trailer. Heater, Air, fans, appliances, Lights. Look for tags that show the ratings. If it is in Watts change it. Watts = Amps x Voltage. Voltage will equal 120. To change wattage the formula would be Watts/120 (The Voltage) = Amps. Say you have a 100 watt light bulb. 100/120 = 1.2 amps. After you add up every single thing add in another 30 to 50 percent for compressor start up and items you forget or decide to add on. I would wire for the highest amps, put in a fuse box with plenty of expansion space. This is an engineering approach, which will cost a bit more, although it gives plenty of safety factors and plenty of room for decisions of expansion after the fact. If you short change your self in the future you have a underrated trailer that has to be reworked. Also you have more value in the trailer if you change out, a higher rated system gives a future owner the capacity to do what they want, a strong selling point. I would strongly recommend the wiring and setup is worked over by a licensed electrician. RJF

Richard,
That is exactly what I needed on that topic, thanks. And sound advise.

DJTomatoe,
Thanks, yes it does help. So you run three shore lines, one each from a 20 amp outlet? Yes?
Lance

i run three cords to city power,,,each cord carries approx 20 amps or just a bit less

It's not home-made it's "Professionally Hand Built"!

Ahh, yes Jack. I apologize for the vernacular. I will certainly describe it as professionally hand built when and if I go to sell it...might as well start now. Thanks.
