I'm installing a 1/3 hp 5.6 amp 115 v. Liberty sump pump w/ float switch in a basin in my very cramped dirt-floor crawlspace, to remove seasonal high water-table flooding. I pulled 12 ga. Romex from the panel about 75' to a single-gang receptacle box in my laundry room wall. I then spliced and pulled a short length to another single gang box at the c.s. ceiling and installed a duplex receptacle to plug the pump into.
Circuit is dedicated, and will operate off a 15 amp GFCI breaker. Acknowledged that the manual calls for the pump to be plugged into a receptacle 4' above the finished floor above, which is problematic for a number of reasons- tile floor; no room to install another receptacle next to the stackable washer/ dryer above the pump, if it needs servicing, would need to pull the power cord, etc. I feel confident that were a 100-year flood to occur that flooded the full height of the c.s., the breaker would trip, and that would be that until water subsided. I'm not an electrician, just an ignorant homeowner, and could be wrong.
I have a couple of other questions:
I would like an indicator (preferably green and red neon or led lights) mounted in the laundry room box that will do 2 things: tell me when the circuit is energized, so I know the breaker hasn't tripped, and also to tell me when the pump is drawing current, so I know when / how often it's operating. Is this possible with the current wiring setup? I could install another receptacle there for an indicator and wattage meter, but would prefer to tell at a glance what's happening.
I got a 20 amp GFCI breaker before I settled on the current pump, which now specifies a 15 amp breaker. From what I'm reading, I should probably go ahead with plans to install a 15 amp instead of 20 amp, correct? Is there a risk of fire by using the 20? Thanks.
