DIY Electrical / Conduit ?

[imperator]

I'm in the middle of running my H2O plumbing. Next up is the electrical conduit. A few questions for this step:

Can the elec conduit run in the same trench as the H2O plumbing?
Are there any depth requirements for the electrical pipe?
Do they typically run multiple wires in one conduit or is it usually a home run to the pad or transformer/junction box.

Sharing the trench is fine.

Depth requirements vary all over the place depending on voltage and concrete above or not, etc. It is always a good idea to check with your inspector (if you require an inspection) to avoid extra work changing things later.

Sharing conduit is allowed in some situations, and not in others. Generally if everything is GFCI protected you can share, otherwise not, but the actual rules are more complex than that.

Generally, each light runs on it's own to it's junction box, which has various location requirements, and then from there back to the panel. The run from the junction box back to the panel is sometimes shared, especially if the lights are on the same circuit.

In my jurisdiction, depth requirment was 30 inches I believe UNLESS it was covered by concrete in which it could be shallower.

Thanks so much for the help!

Low voltage has to be separate from 120/240

Also depth depends on type of conduit being used
