Wiring Opinion?

[islandtrader]

I'm almost done putting in all my windows and thinking about the next stage.

Any consensus on: Do you put the wiring in first and then insulate? Or insulate and then wire?

Or do you make that decision after you decide what type of insulation to put in.

If I remember correctly on my can the wires were first and the pink stuff second.

We wired, then insulated. We used the pink stuff. I don't think that would change if you were to use a different insulation. the wires need to run through the metal supports in the walls, not on top of them. At least, that's how our '72 was set up. I admit I don't know how a '56 would be...

Factory would be to wire first, tape to outer skin in between ribs to support, then insulate.

If you want an alternative; I ran aluminum 'conduit' (5/8" aluminum fuel line from Speedway) inside the walls so I could fish wire/do repairs without removing inner panels. It does require some inner wall modifications where the wire exits to tie into your breaker panel/batteries. There are still short runs of wire on the floor/inner walls. At each end of the tube I flared it so there were no sharp edges to damage the insulation.

Either way, any large guage wire has to be in place before insulation.



I notched the wall panels to extend the conduit down to the floor. (FYI I installed the inner panels inside the channel to direct any water leaks away from the sub-floor. Areas around the conduit will be sealed with alumiinum tape.)



At fixtures/recepticles the tubing stays inside the walls. Edges of the wall panel hole are deburred and covered with tape/crommets as needed.



If wiring goes into a cabinet (kitchen above sink) I bent the end of the tube to extend past the wall.

Thanks everyone ...I really did not want to insulate right now anyway...LOL
