Can Romex be exposed in garage?
No, you cannot expose Romex wires or non-metallic sheath wires in the detached garage or anywhere. Because it’s not safe to expose it on the outside. Besides, it goes against the National Electrical Code or NEC.
Does wiring in crawl space need conduit?
The answer is no. Nor does it need to run inside a conduit. It would not be subject to physical abuse as long as it was kept between the joists. The standard NM cable of today has conductors with a THHN rating.
Does 220 wire need to be in conduit?
No, there’s no such restriction. If your circuit requires a neutral it must be run with the hot wires (conduit or in cable), similarly with the ground. However, if you don’t need the neutral, you don’t need to run it ( conduit or not).
How often should Romex be stapled?
General Cable Support Runs of NM cable must be supported at least every 54 inches. 1 They also must be secured within 12 inches of an electrical box that includes a cable clamp or within eight inches of a box or enclosure without a cable clamp.
Can you bury a junction box underground?
