Electrical- best way to connect 9 #12 ground wires?

Question

Hi,
I have 8 different #12 ground wires in my junction box, that need to be attached to the #10 ground coming from the electrical panel. I tried to use a blue wire nut, but all the wires will not fit. What is the best way to attach them? I was thinking I could connect four and four, and then with another wire ,connect each group to the panels ground, but was told not to do that. What is the best way to get all of them connected to the ground?

Thanks for your time

Answer 1

If these are ground wires try installing a ground bar in the junction box and attach the wires to that.

Answer 2

connecting 4 wire to another and the other four to that one is ok by code (make sure connecting wire is about 10 gauge)
Or use a split bolt also klnown as a Burndy

These are actually for size two wire, but when your have that many wires, you'll appreciate the size of these connectors.
After connection is made tape it good

Answer 3

Depending on the size of your j-box, you could get a 10 spot ground bar and let it float in it if it's a plastic box if metal you'll have to attach it to the box, but you can do as you said do a couple of smaller bundles with a jumper in between them.

Answer 4

You should run all the wires to the breaker box and tie them into the ground bar. If that's not pratical then twist them all together and solder them together.

Answer 5

Go to a supply house and get a split-bolt connector.. They are made to connect heavy wire...They come in different sizes.

Answer 6

Bring them together close as possible in a circle, then take a piece of uninsulated copper wire and wrap it around them making a coil. Then get a propane torch and solder and flux and solder them together.

Answer 7

From the source you have a black, white and floor, the two 14-3 have black,pink, white and floor. tie each and all the grounds jointly then tie the black from the source to between the white going to between the switches from that change you have the black and pink tie them to the cord going to the different change pink to pink black from the 1st change to white on the 2nd change at that element you might have purely a black and white left on the mild those bypass on your mild. your switches have 3 screws plus a floor screw bare copper cord to the floor screw, 2 screws are on suitable and a million on the backside, on the 1st change tie the white to the backside one and the pink and black to the different 2, on the 2d change white and pink bypass to the right screws and black on the backside screw
