Electrical Conduit Repairs

An electrical conduit refers to a piping system that is designed to route and safeguard electrical wires. Conduits can be constructed out of plastic, metal, fiber, and fired clay and are usually installed by electricians at sites where they are installing electrical equipment. Wiring regulations like the U.S. National Electrical Code or local code typically lay down rules for the use, form, and installation of conduits.

Listed below are a few questions answered by electricians on issues relating to conduits.

How do I pull new wire through a conduit that already contains a few wires?

What you could do is take one of the wires already present in the conduit and pull the new wire, along with wire pulling lubricant. Then replace the wire that you used as a pull.

Does an underground cable have to be in conduit after leaving the pole and before reaching the house?

You don’t have to do this although it is highly advisable that you do. It would serve as cheap insurance and prevent you from replacing or repairing the cable in case a stone damages it.

Can you give me a few tips on how I can free a stuck conduit locknut inside an outlet box? I only have access to the inside of the outlet box.

Use a screwdriver and a pair of lineman’s pliers to help you. There are two ways to do this. The locknut will either break free and begin to turn, or you can go on hitting it till it breaks off. Thereafter, you can lift it off the pipe. If you use Klien locknut pliers, you would need more room to help you and in the event that you might have distorted the edge of the locknut, the pliers won’t be able to get a hold of it.

I need to replace a rusted conduit pipe that feeds our house with the mains electricity supply. Unfortunately, this runs through an acre of rocky undulating bush. How can I go about doing this?

You would need to find a local Vermeer Trencher rental or an excavation contractor to help you get the pipe replaced.

In Marysville, WA, how deep does one have to bury a Type UF-B outdoor cable to comply with code?

This kind of cable needs to be directly buried without conduit, and it should be buried 18” deep.

If you decide not to use conduit, do you need a service head?

This would all depend on the needs of your utility. For example, some utilities allow a goose neck on service cable while all the others require a weather head. You wouldn’t need to run conduit to use a weather head since it is made up of metal and PVC.

Conduit needs to be cut properly during the installation process so that it works well and is compliant with building and zone codes. To begin with, remove all wires inside the conduit before you start on a remodelling project. Then, decide how long you want the conduit to measure and mark the measurement. After this, mount the conduit in a vise, in such a way that it doesn’t twist or move. Then use a hack saw to cut the conduit and ensure that the cut measures a perfect square (90 degrees) at the end of the pipe. Finally, smooth away any burrs or shards with a carpenter’s file around the cut.
