I bought a GE multi-use panel model number TM1210CCUG from the BORG and I was, at first, surprised at the layout. The panel is a 100 Amp breaker panel that is designed for use as either a main or a sub-panel. It contains a factory-installed 100 Amp main breaker that will serve as a cutoff in my workshop which is detached from the main house and is about 45 ft away. I will feed this panel by tying two hots to the 100A main breaker to "feed" the bus bars. I'll use a double 90 Amp breaker at the house to protect the #3 THHN feed wire in conduit. Two hots, 1 neutral, and a #4 ground. Maximum amp draw at the shop is expected to be 60 Amps occasionally, but 30 Amps normally. I'll have a 30 Amp feed to my camping trailer next to the shop and plug that up just before trips or once a month for maintenance.
I'm located in rural Tangipahoa Parish, LA and will not have inspectors to please; just the peace of mind ruling that I go safest possible route.
I'll post a picture and declare what I think I know about this, what I think needs to happen for my particular use of this breaker panel, and then hope for affirmation and or correction from the SC gang. I personally like to feel secure in what I do when installing new electrical. Thanks in advance.
The box came with an installed ground bar and what I believe are two separate neutral bars. This confused me a little at first then I remembered that some manus brag about twin neutral bars for ""speed and convenience".
- First - what I think I know. The left side neutral bar has two lugs?? I believe that is so that the incoming neutral can land on one lug and a "jumper" can go from the second lug and tie in the neutral bar along the right side of the breakers. I do not see a "tie bar" as some boxes have so I must ASSUME (that word gives me pause) that It is OK and necessary to use a #3 wire to connect the two neutral bars.
Next - the right side neutral bar has a green screw that must be removed.
The small grounding bar on the far right is where all the bare or green equipment ground wires land and a bare wire shall connect this bar to a ground rod placed in close proximity to this sub panel.
Thanks again from all you sparky-knowledgeable woodworkers. What a great place to hang out and exchange ideas!
