I'm running an 8 gauge wire from the breaker box to my pump (which is 200 feet away from the house).
I want to install a switch near the breaker box and want to know if I can use 10 gauge wire from the breaker to the switch and still maintain the proper amperage for the pump (i.e. so it won't overheat).
The hypothetical diagram is:
220V breaker | | 10 gauge wire (under 10 feet long) | switch || || || 8 gauge wire (approximately 200 feet long) || || pump
The question is: Will the 10 gauge wire mess up the run or will the pump still work right?
