Outdoor PVC to panel question


Any advice on how to connect an outdoor 1" PVC pipe to the main house panel?
The 1" will have 3 6's and ground coming from a disconnect box and spa. The main panel is in a exterior wall on the outside of the home. I'm going to have to have to come in thru knock outs in the bottom of the panel and I can get the exterior PVC pipe less than a foot away from the panel.

One possible idea was an lb box to go inside the wall and then use smurf tube to the panel but I can't find 1" smurf tubing.

Any ideas?

First off, are you using gray PVC conduit (not white PVC pipe for plumbing)?

You are doing this the hard way.

Simply cut a 1-3/8" hole through the back of the panel, directly to the outside. That is where you put the LB on the outside. You don't have to use the factory knockouts, you know.

I was planning on using the gray piping. Thanks.
I wish I could drill stright from the panel to the outside wall but the panel, like many homes in south cal, open from outside.

Why not just run PVC all the way into the panel with pull elbows and the like, and just strap it to the wall?

Use one of these with a lock nut and bushing.

How about posting a picture of your setup? If the panel is outside, it should not be a problem ... unless .... is that panel recessed into the wall, and only accessible from the outside?

Glad you asked. The panel is recessed into the wall and opens from the outside.

Can you switch over to seal tight conduit just below the panel anf transition into the wall into a KO? Sealtight is flexible like hose.

Yeah, they always seem so mellow. Way cooler than the outside panels in AZ, but not as cool as the panels in AK.

Not a big fan of those outside panels either.
By seal type, do you mean the same thing as liquid tight?
I was thinking to use an LB box to enter the wall and then it's a sharp 90 to the panel bottom. Maybe to sharp for liquid tight.

Or do mean to change to liquid tight before entering the wall... Hmm.

Use a 1" "Bushed Elbow" (sometimes known as a Telephone Ell) beneath the panel. That should get you out the outside wall. You might have to use a couple of 1" conduit nipples.

Bushed elbows come in 2 lengths, long and short Get the long one so that the conductors have bending room.

Put an LB on the end and you're home free!
