GE split Buss panel

[Beemer533]

I have a colleague at work that asked me to look at his panel (well, pictures of it anyway) because he wanted to add a hot tub.

Looking at the pictures (which I don't have) the panel is a GE split buss from the late 60s (house was built in 1967).

The panel is fed directly from the meter (about 6' away) with 4/0 XHHW-2. There is no disconnect at all between the meter and the panel. I am aware of the "6 throw rule", is that still acceptable?

I told him he should probably have it replaced either way as the panel is pretty well maxed out, space-wise. Also, his only ground is to the water main on the other side of the house, which could be fixed separately, but I would just fix everything...

This is more for curiosity, as I have not run into a split buss panel before.

For a multitude of reasons, some better than others, it would be good to replace it with a modern panel with a disconnect.

The AHJ will let you know if the 6 throw rule is allowable on upgrade or heavy-up or remodel. Most I work with in VA and TN require a main in the panel.

They were used as they were less expensive (did not have the main breaker/disconnect) and many were from commercial lighting jobs.

best of luck.

The six throw rule is still in effect, but split bus panels are outlawed.

For new installs I assume.. Are existing ones grandfathered?

Yes.

It probably has a space in the top section that would be perfect for a breaker for a hot tub.

Why spend all that money and time replacing something that is in good shape and which still has breakers readily available and has functioned well almost 50years with no problems?

Not sure what code you're on there but a new panel will require arc faults on all the 110 circuits. That's expensive. Plus a new panel will have to be full of wire nuts as you will probably have to lengthen your neutrals and move breakers from one side to another.

If the lugs are in good shape I.E. not charred or worn, why replace it?

I agree, it works, but the top section is completely full. I suppose he could just put in a sub panel.

GE makes up to a 125 amp breaker that fits into a regular 2 pole space for the subpanel.
You could take the smallest load in the top section (except the one power the bottom bus section) and transfer it to the subpanel....... and have as many extra breakers as you want.

Yeah, that is probably the best way to go for him. Thanks.

Subpanel is probably your best bet. Make sure to put in ground rods...
