Pool Heat Pump

[late night]

Hi all,
Our electrician cancelled and the pool pump installer is coming Friday so I need to do it myself. Not a big deal, very simple, straight run, I just need advice.

The pump requires 40A, single phase, 50A recommended and 60A Max. We have two 150A panels 60 feet down the same wall so I'd like to run along the wall in some form of conduit.

Not sure about a few things.

First, do I need a fused disconnect at the heater end - the heater is around the corner about 20 feet from the pool.

Second, the entire run is outside. Is THHN OK?

Third, I'd like to make it a 50A run but if I need a fused disconnect then all that Home Depot has is 60A. What size wire?

Fourth, what conduit should I run it in?

Thank you very much

Sir, In the UK this wiring could only be done by a competent electrician because a pool is a special location with particular hazards to be protected against. I suspect the same is true in the US. Legal liability comes into play with the risk of prosecution in the event of harm, injury or electrocution.

Late night first off yes put in on a 50 breaker, since you are using THHN it is approved for wet locations. No disconnects fused or not fused are needed. So you need one 50 amp 240vac GFCI breaker, use # 8 THHN wire x 3 and one green # 10 THHN equipment ground, and 3/4 PVC conduit would be the easiest. Your disconnect is in the panel the 50 amp breaker. Welcome to the forum and good luck

Thank you Megawatt. I completed my part yesterday. I did go with a fused disconnect because I didn't see your message until now.

If you ever run into something like this again you should have used a non fused disconnect.

It's designed for pools and spas so I jumped.

Thanks again
