Check to see the local code requirements.
Coduit entering building from ground siding.
I am assuming a coupling underground is damaged causing the conduit to fill with water when it rains.
The male connectors on the ends of the pvc conduit take up quite a bit of room inside the box leaving little room for devices.
In this way the metal raceway acts in place of the grounding wire that is found in nm cable this is also the main reason why only metal boxes may be used with metal conduit.
Six inches would not be too far.
Make sure you have at least 1 inch of conduit exposed between the wall of your structure and the end of the conduit.
This is what happens when wood siding is too close to the ground.
The conduit should be supported and then the fitting will be supported.
Wood siding should be 4 or so from the ground whether that be soil or solid surface.
The lb fitting has no means for support.
Start from the inside to ensure that the hole is centered behind the junction box drilling out through the siding.
For under ground conduit coming up in to a panel or building duct seal.
Whatever size conduit you use don t fill it more than 40 percent with wires.
Wiring in pvc conduit must have at least 18 inches of cover.
If a pipe is running under ground down hill concrete pull box with drain rock at the bottom of the hill.
Wiring buried inside rigid metal rmc or intermediate metal imc conduit must have at least 6 inches of earth cover.
It gets wet it rots and it attracts termites.
3 besides the access.
Uf cable can be direct buried without conduit with a minimum of 24 inches of earth cover.
What is on the other side of the wall.
In some installations using metal conduit the raceway the conduit boxes and connectors serve as the ground for the circuit.
2 yes the conduit runs underground between the garage and house and it enters the house under the ground line.
Some codes may require rigid metal conduit where it emerges from the ground or some may allow a heavier wall pvc.
Use outdoor silicone caulking around the conduit at the structure in order to hold the conduit into place and keep water from going inside your structure.
For under ground conduit coming up in to a panel or building duct seal.
Step 3 attach the lb fitting to the pvc conduit using pvc glue.
The further the better.
1 the garage conduit is dry and the entrance point where the garage conduit enters the ground is dry.
You may slow it down from above ground entering by seal offs but thats.
Single gang electrical boxes will work but if you have two or more conduit sections connecting to one box buy double gang.
