Installing Electrical Circuit Wiring for a Sump Pump and providing the necessary GFCI protection and means of disconnect.
Wire Size for a Sump Pump Circuit
Electrical Question: I plan to put a separate circuit in for the sump pump in my septic system.
- I have a Rigid 1/2 horse pump (10.5 amp motor) and will be using a 20 amp breaker.
- The wire I have on hand is 14 gauge.
- Is this an adequate wire, or do I need to get a larger gauge?
This electrical wiring question came from: Duane, a Homeowner from Ravenna, Ohio.
Thanks for your electrical question Duane.
Electrical Wiring for a Sump Pump Circuit
- The wire size that should be used for the 20 amp septic sump pump circuit should be #12 gauge.
- The sump pump should be protected by either a GFCI outlet or a GFCI circuit breaker.
- A means of disconnect for the sump pump must be located within sight and readily accessible.
- If a receptacle outlet will be installed then a weather proof cover must be installed to offer protection from the weather even while the sump pump is plugged in.
