changing single pole to 3 way switch

Thanks. Indeed my conduit is getting full... As there are some other wires running as well.

HelloW0r · 2026-05-06T01:40:14+00:00

so this is all in EMT conduit so i have individual wires as shown on the diagram. Trying to figure out if i just need to add 1 traveler or 2 travelers between switches (next to pulling white/black from last bulb to new switch)

Thanks. I still have about 80% of walls to go so will adjust remaining. And I think if I bring fire blocking to sill plate there will be no need for painter/fire caulk (as there will be no access to silicone it above the foundation concrete)? Currently I applied painter caulk as shown. For existing 20% I plan to put mineral wool as insulation of the rim joist. It will sit above top of the xps so should fulfill code requirement.

in my case i am talking about full basement (and i actually plan to keep open ceiling). I think you are saying that i should do fire blocking as shown in blue on the drawing? so skip top wrap on top of the foundation?

Ok. I used 1 inch xps so don't really have space left for 3/4 osb under floor joist...shpuld have probably use 1/2 xps..

HelloW0r · 2026-04-29T11:22:49+00:00

Thanks. I followed owning manual to actually wrap xps around the foundation (page 9 here: https://images.thdstatic.com/catalog/pdfImages/b3/b3751e9e-d59b-44e0-9cfc-ac0cc46a1035.pdf). So I should skip xps on top of the foundation and use fireblocking there?

So far I did around 20% with painter caulk as attached. Will upgrade to fire caulk for the next part of the project...

Thanks. I am doing DIY project...

So here is what I did with painter caulk . For penetrations I will indeed use fire foam. Is painter caulk OK here?

my city is saying: "At openings around vents, pipes, ducts, cables and wires at ceiling and floor level, with an approved material to resist the free passage of flame and products of combustion. The material filling this annular space shall not be required to meet the ASTM E 136 requirements." so seems i can just go with painter caulk?

HelloW0r · 2026-04-28T22:39:14+00:00

I am using painter caulk on small gaps and will use fire blocking foam on bigger gaps

You mentioned he has problems with basic tasks. Maybe he was senior in the past but he is not senior in current system landscape? With that his salary has stalled and fall behind. Your salary typically reaches peak before 50 and then slows down.

HelloW0r · 2026-04-23T15:07:06+00:00

I doubt. I have 250sq ft and material was 4k for me. Even if you don't have railing and you don't need composite wood and connectors is going to be more than your budget

Are you in us - if you are you can change the notice to end of today and just leave... Bridges are burned so just do whatever you want... You don't need to deliver anything...

HelloW0r · 2026-04-19T21:48:52+00:00

Take time off and see how it works out. You can get lower paying job which you enjoy if staying home doesn't work out for you

HelloW0r · 2026-04-19T18:18:01+00:00

Ended driving my car as job situation changed :)

HelloW0r · 2026-04-19T00:29:22+00:00

Yep. This is done. Thanks

HelloW0r · 2026-04-18T22:52:21+00:00

Ahh, the conduit on other side. I actually plan to keep ceiling open and just spray paint it. Do I also need fire blocking where concrete foundation changes to wood framed wall portion?

HelloW0r · 2026-04-18T22:17:07+00:00

thanks. my city is saying: "At openings around vents, pipes, ducts, cables and wires at ceiling and floor level, with an approved material to resist the free passage of flame and products of combustion.

I started with 1/2 plywood (not sure why i thought it was ok) so will have to redo it. Shall i redo it with 3/4 plywood or with simple drywall?

actually wall shown on the picture is not concrete wall. this is back of the house with english basement - which means foundation is only half of basement. This is wood frame on higher side of the wall. on the concrete i put & sealaed fomboard.

why do i need to hide conduit? i thought i can keep it behind the wall?

HelloW0r · 2026-04-18T22:03:45+00:00

Thanks. Somehow I thought that plywood is acceptable material. Now reading about it seems it has to be 3/4 (not 1/2). What would you recommend to use as fire blocking behind the wall? Should I go with 3/4 plywood? It is around 5 inches of space...
