TECK Cable vs NMWU

Yes it does matter.

It is best to get a LEC to visit and explain what is required for your installation.

Code does stipulate when NMWU can and cannot be used. Teck cable is almost always usable in all locations and the better route to go.

But BOTH cables can be damaged and should be protected from these harms.

Thanks for the reply. My intent was to bring it from the house in about 8" of sand at least 30" deep to protect it.

you will need to contact ESA and book an inspection. For a few $ it's the best way to ensure it is done right.

As mentioned there are many rules that must be kept in consideration and the ESA will guide you right.

Hi Neil

It may cost a little more but pull a permit as the homeowner. You'll get all the answers you need at that point. Just be sure to have it drawn / mapped out.

Permits also support resale..people like knowing things were done to code and have documentation.

Hi Neil

The difference is really the protection you are going to use. I always recommend to clients to use conduit in the ground vice burying a cable directly. This leaves options for the future changes if required.

You cannot run either of the two wire types in conduit, but you can run them in a protective sleeve or chase. You require a trench inspection by ESA before putting the wire in complete with marking tape. The trench inspection is part of the overall permit that you need for all the work that you are doing for your garage.
