Need details for pool / pump wiring?
Im installing a new filter system using A Jandy Stealth 1hp pump. Max load is 7.8 @ 220v. Pool light is 250W. I plan to run THHN 10AWG wiring in PVC conduit underground. I'm connecting to sub panel with 30A breaker (2phase). At filter site I plan to use 15A 2-pole GFCI for pump, and 15A 1-pole GFCI for light. Using Timer and Outdoor load center.
Does this arrgmt seem on track? Does their need to be a GND rod at filter area to bond the equipment?
Thanks
It sounds like you may be on the right track. The wire size is dependant on 2 things: a) The load being served, and 2) The distance from the source. You seem to have the load size part of the equation correct. The distance part is easy, too. If your sub-panel is 100 ft or more from your main panel, you may want to install a larger size wire. This is due to the resistance of the wire causing a voltage drop at your sub-panel. Nothing burns out pump motors like insufficient voltage.
You should bring out a 4 wire feed to your sub-panel. This would be 2 "hots", 1 nuetral wire, and a ground wire. Code in my area also requires you to install a ground rod at the sub-panel. You shouldn't need another ground rod at the filter area, but it wouldn't hurt to install one, either.
The National Electrical Code has specific requirements for swimming pool installations. You should be able to find a copy at your local public library. If any of this makes you nervous or you think its too much for your skills, call a professional electrician.
