How do you run cable through a crawl space?

If you’re running cable through a basement or crawlspace, drill a hole in the bottom plate directly below the box. Feed your fish tape into the wall opening, pushing it up into the hole you made in the top plate. If you’re running cable through a basement or crawl space, push it down to the hole in the bottom plate.

Can you run Ser cable underground?

SER is not constructed for underground use. You need a UF or USE cable or THWN/THWN-2 wire if I understand your application properly. You might want to consult your local electrical supply shop as they would be in a better position to get you the right cable for your job considering local code requirements.

Can I use SER cable for subpanel?

SER is a perfect cable for feeding power to your sub-panel, and, depending on the amount of amps their sub-panels are handling (we’ve seen everywhere from 50 amp to 200 amp sub-panels being serviced), our customers are using all sizes of SER as a sub-panel feeder.

Can Romex be used in a crawl space?

If your crawl space is normally dry, you can use non-metallic wires such as Romex.

What is the difference between SE and Ser cable?

Style SEU cable has two phase conductors surrounded by a concentric neutral while the SER style has two, three or four phase conductors and a bare neutral.”

Can Ser go in conduit?

Replies. SER cannot be placed in conduit if you intend to bury it. If it is at least 18″ or greater above ground, then it can be placed in conduit for additional protection if preferred, but just a reminder to use conduit that maintains at least a 40% free-space within the conduit.
