I am planning to run a new electrical wiring in my backyard and start from where the current outlet is at the wall (behind my kitchen):
It's right above the deck and here is the picture under the deck (about 4 feet tall)
I plan to run the wires under the deck using all PVC conduits. However, I am wondering how to connect the new wire from the wall.
I am thinking of two options.
Pull the wire through the bottom of existing box and box cover like this
However, the current electrical box/cover is very flat to the wall. I don't know how to pull the wire through the bottom like the picture.
This leads me to option 2 which is to run the wire inside the wall first, and then pull it outside the wall through a LB box under the deck:
But to be honest, this option is too complicated with many small parts: nut connector, EMT, conduit connectors, LB, RMC, 4x4 box, seal ...
I am leaning toward the first option (Option 1). What are the pros and cons? If I go with Option 1, I have to drill a hole in the deck (which is fine) to run under it. But how do I "protrude" the box at first? Do I replace the existing box so it's staying outside the wall?
I added the extension box and ran the PVC through the deck outside.
I will add a strap at (A). Right?
Do I need to put glue or seal around the hole at (B)?
