Extension Cord
We have found ourselves in a spot where we are going to have to live in our camper for a bit and need to purchase an extension cord that will reach the closest power. I am looking at a heavy duty 100...

Sorry, but you clearly don't understand voltage drop in a branch circuit. But what do I know, I'm just a lowly EE. There's really no point in discussing it further...

The OP's original question was whether 100' of 12 gauge drawing from a 15 amp circuit would be suitable for his intended use and the answer is YES. Even assuming a maximum draw of 15 amps voltage drop over that 100' of 12 gauge would only be 4.76 volts.myredracer wrote:
What you are ignoring is the overall length of what the circuit could be. Is it 200', 250' or maybe 300'
Wrong again - the OP specifically said this cable run would be 100', drawing from a 15 amp source. This voltage drop calculator specifies "distance" as the one way distance from source to load. Obviously we have no way of calculating any further loss within the rig itself, nor does the OP - but the point remains that loss over 100' of 12 gauge even when drawing a full 15 amps is still well within acceptable limits.
