Porch Electrical Re-Route

Finished stairs

Finished stairs

I finished up the front stairs by installing a new door at the top (into our apartment) and putting on a temporary railing. With that project complete, we can switch our focus to the back sliding door. Our project flips the back porch layout from stairs on the left to stairs on the right, so the new sliding door is going on the left side, where we currently have stairs going to the second floor. Basically, we needed to finish the front stairs in order to take out the back stairs.

In addition to the stairs, there’s some surface mounted electrical that services the porch that is in the way. We still want lights on the porch, so I needed to re-route it to the other side of the back door. There’s an old rotary switch that controls the lights on the first floor and the basement, and a line that goes up to the second floor for a separately switched light and an outlet, as well as a flood light for the back yard.

All of this electrical is temporary, so I just re-used the BX and even the rotary switch. I made the switch inline and put the junction above the door, so that it could connect where there was a break in the existing rigid conduit that goes to the second floor. I left the rest of the second floor stuff alone. I had to move the basement light so that the BX headed up to the first floor would be on the other side of the door, but the wiring itself didn’t change.

Once I got everything re-connected and wire-nutted, it all worked except for the basement light. My circuit tester had gone into the garbage several months ago because it had a tendency to beep at everything except live wires, so I was left with a bit of trial and error. I’ve since ordered a new tester, but in the mean time I had to figure out what was going on. It turned out to be a swapped neutral and live, which I’m surprised even worked as well as it did. With that straightened out, both lights worked.

The only other thing that needs to be done before we take out the porch stairs is to bring down the old steam radiators. Last fall we got them out of the house, but only onto the back porch of each floor. Rather than take them down our new front stair and potentially scratch up the OSB, I’m bringing them down the porch stairs. This is slightly challenging because one of the radiators is actually wider than the steps.

Bay Electrical Outlet

As I was leveling the bay, it occurred to me that before I put down the OSB subfloor, I needed to run the conduit for the electrical box. In Chicago we have to run EMT conduit for all electrical. No Romex wire, no BX armored cable, just hard pipe conduit. Looking at the, er, generous amount of framing I used when we installed the windows, there was no way to run the conduit sideways. The window itself meant I couldn’t go up, and the masonry below made it difficult to go down, but still less difficult than the other options. Regardless, resolving this now, before I put down the subfloor, would be vastly easier than doing so afterward.

Dean came over Saturday and we figured out how to run the conduit with the least damage to framing, brick, subfloor, and spray foam. The box is mounted in the center of the window and the conduit goes straight down before bending at an angle to the left. The shim I put down on top of the brick needed to be cut at an angle so the conduit could pass through, directly beneath the subfloor. Dean notched out the sole plate while I chiseled out a narrow channel in the brick behind the front joist with my rotary hammer and drilled a hole through the joist in the center of the bay.

With some careful bending (followed by some not so careful bending) we managed to get the first piece through the joist and the second piece around the channel and up into the wall next to the front door. That meant we could put down the OSB in the bay, which required just a little bit of notching on the underside to fit around the conduit where it curved up into the wall. Now when it comes time to do the rest of the electrical we won’t have to worry about how to put this in without damaging the brand new subfloor.
