Get to mess up my nicely run power

[Falcon67]

Working on removing about 10x24 of the shop ceiling to allow full use of the two post lift. The sad thing is that there are 11 runs of 12-2 heading across the space in two separate channels. There is no good way to pull the runs back out of the box and re-route, so it looks like a huge cut-n-splice party. I'm thinking two 12x12x6 boxes should have plenty of fill space to home each end. Can't decide whether to punch one big hole - like 2" - to run wired in and out, or cut several 1" holes and kinda separate things in a little bit of order. Both will be mounted where they are easily accessible later, of course.

I'd not have to do this if I had really looked at my layout and realized that I put the main panel on one end of the shop, but 80% of the circuits ended up on the other. Hah. There is no place to do that now and even if there was, it'd be hella lot more work because everything is boxed in, floored, covered with storage, etc. Easier to just label, cut and splice.

Most of that stuff run through the studs will get pulled back. Bummer

I vote "Cut n Splice" party... 12x12x6 should be more than enough. Carbide hole saw and romex clamps would be the way to go.

You can wire nut or wago. But the slick way would be with DIN rail and terminal blocks.

Box fill... I cannot tell you how many industrial boxes of that size I have opened and a nest of stranded "jumps" out of the box.

Now you've made me go from thinking "a maze of twisty wires, all alike" to "Hmmm - DIN rail..."

I vote DIN rail and screw terminal blocks. I won't go into the 'screw vs spring clamp' debate (been done already)

I did something similar under my house. Nice thing about it, you can color code the TB's....as well as group them according to ckt.

That looks very clean.

About 5 years ago, I decided to raise the ceiling and install some skylights over the 3rd stall of my garage (the other 2 stalls are under the 2nd floor). As luck would have it, every electrical circuit in the house ran through this area. Air Conditioning, sub panel feed, plus a sh*t load of 15 and 20 amp circuits. I just took it slow and easy, cutting and splicing in about 5' of wire one circuit at a time

Git - VERY clean work in that center photo.

ddawg16 - Very nice work also..

But I am confused...

Almost all your conductors go straight through..

Could have used wire nuts w so few splices.

I guess I'm just not used to Term blocks except in like control panels.

No problem though, looks nice.

I assume the can is grounded ?

That is basically a pull box.....

I added 18' on to the back of my house and had to move my load center to the back of the house.

The conduit going down goes under my slab and over to my load center.

The big conduit on the right side goes over to the existing part of the house to another pull box in the crawl space.

Another conduit goes up through the wall to the attic....

All those ckts supply power to the existing front part of house.

The wires you see on the TB's are GFCI power for utility stuff in the crawl space. I have lights down there and one of these days I'll add an outlet in case I need power.

+1 I agree!

I wish I had seen that example when I had to make splices in the attic.

Ok... Allen-Bradley, Seimens, Phoenix Contact, Wago, Automation Direct as well as a host of other distributers and manufacturers have extensive lines of terminals accessories.

Was there something special about the Bussman series? Personally had never used their terminals.

Good news is I can move a 30A line without a splice, eliminate another 20A and end up with only 9 to splice. Probably just do the wire nuts as I can get to it with Thanksgiving days off and not have to order parts from somewhere. Off to Low Depot or where ever.

Marc & Larry - thanks for the kind words


I tried to use the KISS method

Two circuits per box. Line in on the left side of the box with the new'spliced' line right on top made it real easy to wire nut things together without getting anything mixed up. Repeat for the right side of the box. Before you know it, your done

I did have some heavier lines for the Air Conditioner - but I just used the blue wire nuts

Finally got this done. The south side runs had to be sectioned and spliced. I got lucky as the 5 on the north run could be cut, pulled back and re-routed, then spliced back together. Saved a bunchy of wire that way as the boxes were 19' apart as the drunk crow flies.

Bought a bag of Ideal push connectors and that made the splicing go a lot quicker. Also took up less space in the boxes than wire nuts. Worst part was laying on that bitty board and pulling 5 long 12-2 cables back through the holes in the studs. Now it's just hacking lumber LOL.
