Can I strip Romex and run in conduit?
The application of Romex wires is limitless, but most DIY-ers often find themselves confused about whether they can strip Romex and use it in a conduit outdoors. The answer is a resounding yes.
Do you have to run Romex in conduit?
Code and common sense both dictate that Romex shouldn’t be left exposed but must run through conduits. If you are running it through the basement or attic (or both), the wire must past through studs or be secured on top of joists or trusses.
Can you bury Romex cable in conduit?
Romex cannot be used in the situation you describe as buried conduit is considered a wet location. You must use conductors such as THWN. That being said, run yourself a 1″ PVC at 18″ depth and pull all your current and future need conductors in one shot.

1/2″ would be fine for up to 4 #10 THWN conductors (you’ll need 3). I might size up a bit just to make the pulling easier. You need to be down 18″ if you’re using sched 80 (which is advisable).
What size wire is good for 60 amps?
For 60 ampere breakers, electricians and professionals suggest using a wire size gauge ranging from 6 AWG to 4 AWG. All household wires have a rating of at least 600V, so only amperage really matters when it comes to determining wire gauge.
What wire do you use for 50 amps?
50 AMP Wire Size For a maximum of 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances. However, a kitchen oven can alone require 50 amps. Many electric dryers also require a 50 amp breaker.
