However, as Tom (TDF-Texas) explained about voltage drop and wire gauge, you might not be getting adequate voltage delivered to the air conditioner's breaker in the trailer. Electrical code requires 14 gauge wiring for 15 amp circuits and 12 gauge for 20 amp circuits. Nowadays, homes are not constructed with 15 amp outlet circuits, they are typically 20 amp circuits. But older homes may have 15 amp outlets. All the AC Wiring in an Escape trailer is 14 gauge, except for the Air conditioner's circuit which is 12 gauge (per Reace). The reason I would not use a 15 amp circuit to power the Air conditioner is that a 15 amp circuit in an older home is wired with 14 gauge wire, and the further the outlet is from the electrical panel the greater the voltage drop. What if the outlet is on the other end of the house from the electrical panel? In my humble opinion, using a 15 amp circuit for the A/C could be iffy and would make me extremely uneasy.
Carl, you're absolutely correct, but I fear that we've hijacked the thread
In order to redeem this conversation we'll have to calculate the voltage drop across a puddle of water
At least we don't have to worry about gauge, just mineral content.
