I am planning to finish my two gable end walls with osb for added sheer strength. There is a garage door on each end. I will have a ton of 1-5/8” drywall screws from my drywall on the sides but I don’t think those would be best for osb. But I don’t want nails because I want to be able to remove...

The 4' LED fixtures I am using give a spec of 48 watts 4400 lumens and I will probably do a quantity of 12 -14 of those. The fixture literature doesn't list amps but I assume that would be 120V /48 watts = 2.5 amps. A 20 amp circuit would power 8 of these (20/2.5 =8) That is 100% duty cycle...

I am installing some receptacles in metal liner ceiling.

I just discovered that my builder stubbed my electrical entry with 1 1/2” cpvc and stubbed my sink drain location with the piece of 1 1/2” pvc electrical conduit I supplied. I can slip 1 1/4” conduit though the cpvc stub and that is the minimum size for my pull. If it is ok to connect the gray...

Will a soffit light, directly over entry door count as the code required entry door light?. Soffits are horizontal, 10' and a few inches high. If answer is yes then what light would be good. I have a 6" can light left over from a kitchen project and it will fit but may need to be wet rated or...

Code requires a outside receptacle at each man door. I had planned to let my builder finish before I started wiring my stick build with vinyl siding on OSB cladding but I need some sort of fitting for the Vinyl siding to be applied around. I need to get it on the wall before the siding is...
