New Subpanel for pool equipment
Hey guys,
I have an above ground 15' pool and a 1HP pump (11,8A) plugged in a 120V GFCI outlet. I want to add an electric water heater (20,8A), but I realized I'll have to redo the wiring.
I need to
See the attached file for a drawing of all this. I live in Canada, so UF cable are named NMWU if I'm not mistaken.
Do you guys have any comments or feedback on my plan?
Thanks,

I need to
- Add a new circuit (60A Breaker) to the Main Panel to feed the new subpanel
- Bury PVC 1-1/4" conduit with cables (#6) inside to the new subpanel
- Add an outdoor subpanel with
- 30A GFCI Breaker for the Electric Water Heater
- 15A Breaker for the pump
- No main breaker
- No ground rod

Welcome to the forums.
Canadian codes differ from our NEC codes.
Here.... in the States..... that hardwired 240v water heater would not require a GFI circuit but it could be used if desired.
Your NMWU cable needs to be 6/3 with ground.
Pulling NMWU (UF) cable thru a conduit can be a bear. No electrician will pull UF thru that much conduit. You could consider using single conductor wires like THWN.
Also..... as per the NEC code..... the ground needs to be insulated for pool/spa use which it is not in UF type cable.

A electric panel near a pool ,,,,,,, danger will robinson.
All of the pools I have done are with rigid conduit or brass. The electric code requires a redundant ground to the pool equipment. Putting a plug in for a pump is poor practice IMO. Pumps should be hard wired and not have a cord and cap. Choosing a panel with spaces to add more loads is just asking for trouble later on. Then you may need the main breaker.
I do not see a bond wire going to the pool structure. REQUIRED. So you could have two different potentials, DANGER. That bond wire should be a #10 or larger, UNBROKEN back to the service.
Do not see a light, hope there is not one.
I do not believe that a outlet should be anywhere near a pool. People are stupid and all it takes is some dolt to plug in a extension cord and put a radio on the edge of the pool for the party.
I do not swim in pools if the light is on. My life is worth more than what some for profit company sells a GFCI that says it will protect me. The NEC or NFPA do not have a standard for testing GFCI's. They both say push the button. Found this out when working at a surface mine and locked horns with the OSHA and MSHA inspectors over it. At least that was the way it was when I retired 3 years ago.
