Old Bryant box, what does this mean?


Old Bryant panel in a townhouse built in 1976.

There is no main breaker.

There is this one 60Amp breaker that is marked "Main LTS".

Which I'm guessing is main lights as that's what seem to go off when it is switched. But 60 amps? And the wiring in the panel appears big enough for 60 amps. So my though would be there's a sub panel somewhere. Main panel is in rear corner of basement family room next to outside wall. But I've never seen a sub panel anywhere.

This is my mother in law's place and I've been doing odd jobs around here for 20 years and would swear there's no such panel anywhere.

So I look closer. 60 Amp breaker loops around to the top of the box. I pulled a few breakers and it appears the top 1/3 of the box is isolated form the bottom 2/3s. So the breakers on top all feed through this 60 Amp breaker for room outlets and lights.

Never seen such a thing. Why? Still being done?

That's a split bus panel. Six dp breakers on the top control the heavier loads and the lower panel. This meets the NEC requirement of no more than six throws for the service disconnect. This is an old style and not made anymore, but there are plenty still in service.

It is a split bus panel, the 60 amp breaker is the main for the lower section.

Here is a reference

Actually the mains come into the panel on the lower left with this 60 controlling the top 1/3 of the pane.

Not the ones I have seen.



The top busses are hot all the time and where you put the 240 volt circuits.

Although I guess it could be installed upside down.

So what was the point?

A fake sub panel?

Force people to put all the outlets and lights in the same area?

The 60 amp breaker labeled Mains LTG controls all of the single pole breakers that typically fed the lighting and receptacles in the house. You should only have up to 5 other double pole breakers in that section with the 60.

A split buss panel was limited to 6 throws of the hand to shut off all the power.

Can you post a pic of both the panel label and a shot showing the inside?

People have been known to add single pole breakers on the hot buss (portion not controlled by the main) and exceed the 6 throw limit.

Are you counting a double pole breaker as two breakers? Double pole breakers can have either a single lever throw or two throws that are connect with a tie bar. This counts as one throw. You can have 6 throws maximum to remove all power in the panel.

Ah. 6 throws to turn everything off. So this tandom 60 allowed them to save a few $ not buying a tandom 125 or 150 for the main.

I'll upload a pic if someone can tell me how direct from an iPhone. Internet here is out for the afternoon so my laptop is out of action.

The size of the breaker is only part of the equation. The bus bars, the size of the cabinet, etc are all tested and UL listed for a certain amperage. Somewhere on the panel case is a sticker that says the panel amperage.

iPhones don't have what you would call a file system. And this forum doesn't trigger the API call to allow someone to pick a photo off the "camera roll".
