Question DetailsAsked on 7/13/2014

does a pool pump need its own circuit

my pump keeps tripping because the GFI circuit senses water.

I'm assuming you are using a single-phase 120v pump. Normally a motor such as a pool pump should have its own circuit for convenience during repairs and replacements, and local codes will likely require it. If a GFCI is also required by code, it should be installed such that it doesn't get wet is designed to react quickly to a grounding condition.

It is not sensing water - it is sensing a short to ground, which may be due to water in something or may be another cause, which should be tracked down. And unless this is a GFCI outlet rather than a GFCI breaker, how do you know it is tripping due to a ground fault rather than an overload by the pump.

By code pool equipment does require its own circuit, though you are allowed to run lighting, sound system,etc off the same circuit as long as they are on their own GFCI breaker or outlet so any short from the pump and filter equipment cannot backfeed into the pool lighting/convenience outlet through the neutral or ground.

BTW - cause of tripping might be because the conenction box is not the correct components - the correct NEMA code like NEMA 4 or whatever is required (depends on specific site conditions, if exposed to condensation or to direct rain, etc) so could be picking up water causing it to short out. VERY common in pool areas where the incoming wire conduit from the ground has water in it, so moisture comes up into the box and shorts or corrodes it out.

Electrician should look at entire installation for code compliance while looking for the specific point of failure.
