I need to run an electrical circuit out of my house to my pool's filter. I plan on using a 1.5" Electrical PVC conduit for this run. I've read many conflicting posts on the depth of this conduit. Many say
18" but other claim I can go shallower...12" if it's 120V single circuit 15-20amps and GFCI at the house (which is what it is). The reason I'm asking is that I want to run this conduit along side a wall that has geogrid at about 14" below the surface. I cannot break this material since it's required for this retaining wall. What are my options?Any comments will be greatly appreciated.
PS: I will be having a licensed electrician to do the job but want to know my options before I get to that stage.
