3.) If I went electric the current plug provided to me by the town is 110....would that have to be changed to 220v ?If you have any use of electric at all you'll need 220 amp service. They haven't built a house in years that doesn't have 220 amp service
Uh, You're getting
VOLTS (v) and
AMPS (a) ALL
MIXED UP HERE ...!!!
Amps and volts are NOT the same critter...!!!
(WATTS equals VOLTS times AMPS)
Lets see if I can shed some light from an electricians point of view
Schmelly...YES, do ask the city or mall or premeses owner IF 220
VOLTS can be installed...
And next you'll want to know where the circuit breaker panel is that will feed the outlet you'll be using, and IF there is a double gang 50 ampbreaker on your circuit... that would be fairly standard...
IF you have the NEED, and IF the WIRE SIZE will permit it, it's possible you might be able to get a 100 AMP supply...(the amount of AMPs that can be crammed down a wire is a function of wire SIZE and temperature...
How many AMPS you'lly actually need is dependant on the mix of electrical and propane appliances...
You might find that a
popular configuration is thus:
Electricity for: hood fans, signs, cash register, refrigeration, phone (charger), lights...
Propane for: cooking.
When you look at natural gas appliances ask if they can be re-jetted for propane, or ordered factory propane ready. When considering USED gas appliances, ask your "Professional Propane Dealer" if the used equipment you're considering can be re-jetted for propane...(and I stress the word Professional" - this is not a job for a shade tree mechanic - it HAS to be done properly)...
If the power available at the outlet is only 30 AMPS, you might have to add a complete solar power system (solar panels on the roof, charge controller, batteries, and TRUE Sine Wave DC to AC inverter, plus wiring and circuit breakers) which can power the cash register, phone, signs (use LED lights if you can) and use the AC outlet supplied by the property owner to power the hood fan and reefer box...
You'll most likely want a 50 amp "dryer plug" type connector to plug into the AC outlet the property owner is going to supply...but it might also be different, so you'll have to get a solid answer as to what type recepticle will be available for you to plug into. Avoid poer cord ADAPTORS because high current can generate heat which can start to melt the rubber of the typical power cord adaptors (I've seen it happen)...hardwire the correct plug to match the recepticle
Most reefers are 120 VOLTS, and many hood fans are 240 VOLTS, but if you look around you might be able to find a hood fan that runs on 120 VOLTS...or you can ask a competent electrician to see if a 120 VOLT motor from Granger's Supply could be fitted to an existing hood...
The Circuit Breaker panel ON THE VEHICLE can be 100 AMPS at 240 VOLTS, or whatever your ELECTRICAL CODE or Health Dept dictates...the 240 VOLT incoming circuit can supply 240 volt appliances and also be split into two 120 VOLT branches...
If you can appoach this as an Alternative Power project...REDUCE THE LOAD, and then engineer backwards from the load to the power source if at all possible...
On the other hand, if the property owner sez: this is what you'll get and that's it, you'll have to engineer from the source to the loads (but still reduce the loads as much as possible...
LED and CFL lights help quite a bit, a (cell?) phone charger does not have to be on all the time, and modern cash registers don't use all that much current...neither do supermarket receipt printers...the fans and the reefer(s) will be your big electricity hogs ...
If you supplement your main power source (provided by the property owner) with a 120 VOLT solar set up, you'll want a separate circuit for the 120 solar powered stuff, and separate circuits for the external 240 VOLT power supplied by the property owner... no big deal for a qualified electrician to install
PS...I know of a caterer in my area that has a food trailer, and it has a very spiffy Honda generator enclosed in a nice looking "diamond plate" metal enclosure mounted on the tongue of the trailer...out of the way, quiet, nice looking... completely SELF CONTAINED, no external power needed, can be set up ANYWHERE...the genny is probably 3,000 watts to 5,000 watts (WATTS equals VOLTS times AMPS)...
ABOVE ALL ELSE: outfit your rig with quality in mind...it has to be safe, durable, servicable, and able to pass inspection(s)...
I hope this helps...
