So I have never had a GFCI on my tank as I’ve always been paranoid about it tripping while I’m out of town. Plus I rent my house so I can’t change the outlets. I realize this isn’t safe so I took Brew12 advice from R2R and made a satellite double GFCI box. This will plug into the wall and I’ll have each Apex EB8 run off 1 so if 1 trips I don’t lose the tank. Undecided on how to best arrange and if I want to run return without GFCI as running while on vacation is my #1 most important thing. Everything bought at HD except the Eaton self test weather resistant GFCI which I got from amazon. HD had Eaton ones but not WR and they were $23 each - 2x 14g Husky cords $12 each - 2x Eaton 15a GFCI - 1x nonmetallic 2-gang 7-hole j box - 2x 1/2” strain relief liquid tight cord connectors - 1x cover plate of your choosing. -optional in-use cover if the unit is going inside stand or near moisture.
