Re: [A/S] Another Generator Question

[Matt Worner <wornmatt@xxxx>]

George,

Along with the information on the air conditioners, will need to know 
the size of the main breaker in your trailer. Even though you have in 
excess of 40 amps available from the gen sets, you can't get more than 
30 amps through a 30 amp main. If you check out your circuit breaker 
panel you will notice that there are a lot more brance circuit 
ampacities than there is main breaker ampacity, the rationale being that 
you won't be running everything at once. Assuming both A/C circuits are 
20 amp, if both are loaded to 80% (which should be the limit) that would 
be 32 amps, assuming a 30 amp main (which goes along with a #10 AWG 
cordset which I think is standard) that means you have no electricity 
for anything else, and will probably pop the main after a couple of minutes.

To put it more briefly, the generators might carry the load but the 
trailer may not.
