I am installing an outide lite on a vinyl siding mounting block.
Electricity is available 5 feet away via a duplex outside GFI vinyl
siding mounted outlet.
Question: Can I run 14/3 under the vinyl siding connecting the source
to the lite?
If so, what type romex do I need? NM-B?


*Use MC cable. Attach a bonding bushing to the MC connector and put a
grounding pigtail on the bushing. You may need to use an angle connector
to
go into the siding block from behind.

Why do you need a 3 wire?
To ground the outside lite housing. Thanks for the post. Have a nice
day....


14/2 MC cable comes with a black wire, a white wire and a green wire for
grounding.
