Still working on the wiring and started painting the bathroom. Got a couple of questions:

Question 1 – Electrical
In my service panel, the #000 cables come in from the back, go up the side, and curve into the top connections. This pushes the cable toward the front of the panel, and if I attache the front cover/door plate, the center screw will push into the cable.

I think I need to put some type of spacer to keep the cable off the front edge of the panel. Any suggestions?

Question 2 – Painting
When priming the OSB on the bathroom, the “stripes” (green) are bleeding thru the KILZ primer. I am hoping that the primer will set the green, and I can cover the stripes with another coat of primer before the final topcoat.
Green stripes
Anyone been thru this before?
I think the stripes are just a color dye, and not actual paint. Not sure why Lowes has stripes on the OSB.

Hoping to finish up the wiring this weekend and get inspected next week. Then on to the sawmill !

Not sure about the green stripes but I think the wire should be “stiff” enough that simply forcing it towards the “back” of the service box- it should stay away from mounting screw. If it flexes back into the forward position, maybe the romex connector isn’t clamped tight.

On the electrical, that cable should be stiff enough you should be able to flex it away from the panel, and have it stay away.

For the green stripes, well primer is supposed to cover colors beneath it, just keep laying primer down until you get rid of the stripes… FWIW, you applied that primer REALLY thinly, I can see the color variation in the OSB in that pic… The stripes bleeding through is no shock…

I think the stripes are an aid to nailing matching up with studs. I didn’t have that problem when I primed my OSB, it was not from Lowes and the stripes were black and they didn’t bleed through. I’m about the same place on my project, just getting ready to put the inside walls up. I’m on the finishing touches on the ceiling.

Here is a photo of the panel with the big cables.


I wedged the 2×4 in there to try to get the cable to “remember” to stay in the back, but the one just keeps moving back to the front. Those cables are stiff, and I cannot seem to make any headway in bending them any further. I can push them back with my fingers, but they don’t stay – I guess the 90 degree turn at the bottom is more than 90, and I cannot get the curve any tighter.

I could leave out the center door screw, but someone might install it in the future, and I don’t want anything to dig into and and short the cable.

To qualify myself … I am NOT a electrician but have done a lot of my own wiring and inspected quite a bit in my former life to perhaps assist you?

On the 0000 wire: I presume you are having inspections performed? My suggestion is to route the cable you are having difficulties with to the RIGHT SIDE of the panel. I honestly don’t feel there is enough room in the panel for ALL three 0000 cables routed as shown. The cable should have enough flex to bend and stay in-place that way. Hopefully you have enough “play” to do this? Your inspector would no doubt fail your installation due to the tight fit as is and could possibly cause an overheating situation should all three cables remain as shown.

The “stripes” are placed upon your OSB board for using as a layout pattern for placement of roofing felt paper, etc. in a roofing application and/or flooring application. I would be very careful with the purchase of “panel” lumber at the Big Box stores as they are increasingly buying China made wood products and have been reported to be an inferior product than what most of us are used to purchasing. I recall most U.S. products being BLACK stripes, but don’t remember green used before? Check your panels, they may state somewhere “Made in China” ... I am jealous of your shop – keep up the great work! You should be proud!

hey lew you need to take one of the common wires and re rout it to the right side of your box so that will leave the other common and ground on the left its not good practice to have both commons and ground together in the panel like that.what will happen is as soon as you start running wires in to the panel to the breakers you will have a mess going on in there

hey lew one thing i just noticed is you dont have a ground wire running out from your nuteril bar i hope you run one before you energize the panel and also check with your state l&i for the codes for the ground washington state we have to have two copper ground rods 6ft long and 8 ft apart pounded in the ground and a certain size copper wire depending on the amperage of the panel

Thomas – Hmmm – that is the first I head of not having the 3 cables running together. I have an electrician overseer, and will have inspection done before the power can be connected.

I will see about moving one cable to the other side. It could make things easier with the wiring – thanks.

Tunk Valley – That was an old picture before I had connected the gnd wire. Local code only requires one 8ft gnd rod for permanent power (my temporary power pole requires 2)

This is more recent

You are welcome. I’ve seen the tightening lugs become loose and they’ll cause a “vibration” (Trunk Valley Works would perhaps have a better description?) that then cause heating of the surface and then whatever maybe nearby. May never happen to you, but I’d change it just for safety sake in that new shop of yours?

Good luck, and have fun!

If you are using the water-based Kilz primer, Kilz 2 or Kilz Premium, you might have to change to the oil based primer, Kilz Orginal, or a shellac based primer in order to keep it from bleeding through. Just keep in mind if you use the oil based stuff do it when you won’t need to be in there of like 3 hrs unless you have some serious ventalation.

I am an electrician and you don’t have to move your conductors to the other side of the panel. You have plenty of room and you aren’t going to have any problems with them over there. If you bend the wire it will stay off the front of the enclosure. You will have to bend it at the top and the bottom so that the wire in the middle will be tight to the rear of the panel. It’s kind of hard to explain, but just pushing it back won’t do it.

”...but just pushing it back won’t do it” That’s for sure!

Even if I moved a wire to the other side, I still have the 90 degree bend that wants to push all the wires to the front. I guess I am just going to have to muscle it a bit to get the bend tighter.

I have done electrical work for years (always under a “real” electrician), but never installed the mains of a service panel. These big wires are tough to work with!

BTW – all the circuits will be 12 AWG or bigger (10 AWG for 30 amp devices) – is there a preference for 20amp and 30 amp plug styles in a shop? I was thinking of going with the “twist-lock” type, but don’t know if they are worth it. I would like to standardize now. Got a 220 (20A) table saw and 220 (30A) Cyclone to wire up now, but other tools will be coming. Maybe better to hard wire?

Oh – and we are using Kilz Premium primer. LOML won’t use anything but water based products unless there is no alternative. We shall see how it works out.

If you hardwire your tools you will have to have a means of disconnect (a switch) wired into your tools. I would just use standard 20A-250v outlets for your 220 20A circuits and for the 30A 220 circuis I would use a standard dryer outlet. I wouldn’t use twistlock style unless the outlet is on the ceiling or in an area where you are worried about the cord getting pulled on. Just my 2 cents.

I agree with david9951 that your wires are okay where they are. I’ve done electrical work for years and wired both my house and shop. As he said it is hard to explain, but you need to bend the wire past 90 degrees where it comes into the box and then if it lays back you might have to bend the top out some. Sounds confusing but that wire is thick enough to stay when you bend it. Good Luck! I hope this helps and your shop and land are looking great.
