What conduit to use for 4-5 in piece of wire from a/c to home?

0 votes

I have a 4-5 in wire which is the power for a/c unit outside of home.  With it being so short, how should I go about running it through conduit?

Hi ChrisG,
 
I’m not sure if I understand correctly your description... that part about the "4-5 in wire", so I’ll just explain the way it should be done. I actually did a post on it already, which is here: http://checkthishouse.com/9/house-ac-disconnect.html
 
So, basically you need to have a disconnect in-sight of your condenser and a piece of conduit between that disconnect and the condensing unit. You can run solid wall or flexible electrical conduit between them unless there are some restrictions in your jurisdiction that would forbid using one of them. 
 
Because of the vibration I would recommend using flexible conduit as the final connection.
 
Just remember that control / low voltage wires should not be placed inside the high voltage wires carrying conduit.
Let me know if you have further questions (read the article first), just explain your installation in detail / click “comment” below.
