Please help me with 30 amp ??

Agree on many points here.  You are ok on a 15 amp circuit at home, just don't use a cheap extension cord.

thanks charlie.....i will never stop.   hogone

I would bet the cord is not a large enough gage. You need a very heavy duty cord for a long run. A regular cord can overheat. Remember, the R-Pod would also be trying to charge your batteries while running the A/C , and add to the amp burden the extension cord and house breaker must carry.
When I use my Honda 2000 genny to run the A/C, I shut off my converter charger breaker in the Pod.

charlie:  no apparrent burns/discoloration but the cord seems or I should say is wrinkly (tuff to describe!!) I have no problem trashing if a potentail hazard.   hogone

Originally posted by hogone one other question.   is that cord (the orange one that got hot) shot?  hogone

Your cord is probably OK, just inspect it. Any signs of damage like melted or discolored material and it's trash. Otherwise watch for overheating when in use.

Your tale is an excellent example of the effects of voltage drop on motors. An AC motor is essentially a constant power device. If the applied voltage drops due to a small wire (high AWG number) cord the motor will draw more current to compensate. The effect is more current through the breaker (pop), fire hazard in the cord (sirens), and potential damage to the motor ($$$).

A little understood fact is that a circuit breaker is sized to protect the wire, not the appliance. It is primarily a fire safety device. A 15 Amp breaker will protect #14AWG wire; a 20 Amp breaker protects #12AWG wire. So a #16AWG extension cord on a 15 Amp circuit can actually catch fire without the breaker tripping.
