What is going on here? The main is a 60 amp breaker and the heater is a 100 amp breaker.

main not at the top ? labels backwards? If correct label make sure that 100A C/B has the correct size wire. I doubt that the “heater” draws more than 60amps, if it does it should just trip the “main”

The 60 is the main. Here is the guts.

Peter…


It's a split bus panel. The "main" is just feeding all the smaller breakers below. The service disconnect is the main and everything above it. In other words there is no single main breaker.

Hi to all,


Peter, it is also a sylvania, made after they bought Zinsco out, so expect other problems with arcing breakers against the busses.

Regards

Gerry

Thanks Gerry. I did pick up on the Zinsco origins when I inspected it. I temp’ed all the breakers and wires with my ir temp gun and nothing was out of the ordinary. There were no signs of overheating, arching etc. that one would except to find. Found some double taps, to much wire sheathing in the box on a few wires, and a stranded neutral that had a few strands bent back to make it fix under a lug.

The biggest No-No would be the size of the double-tapped conductors on the top 100-amp breaker. They don’t apppear to be much more than #6.


With all the double-taps, and if all the circuits are in use, then the panel is inadequate, which makes it an easy "replace" or "upgrade" call on this "Zinsco-by-any-other-name".

This panel has no single ‘main’


Yes this is a split bus panel and it looks from the picture to be a 200 amp upper section served with 200 amp aluminum service conductors.


The breaker labeled 'main' is only the service disconnect for the lower bus section and the branch circuit breakers below it.

The power from the utility comes in on the large service conductors that connect directly to the upper bus of the panel.

Then we have a total of 5 service disconnects connected to that upper bus.

1) Heater

2) Oven

3) Air Con

4) Dryer

5) The one labeled 'Main'

In order to kill all the power to the house all 5 of these service disconnects will have to be opened (off)

The only way to put a total rating size on this service is to verify the rating of the service conductors, upper bus section of the panel and the meter socket.

The rating is not the total of the 5 service disconnects.

Are the best thing that ever happened to our electrical forum.

Thanks guys ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif) ![icon_biggrin.gif](upload://iKNGSw3qcRIEmXySa8gItY6Gczg.gif)

Peter,


I would not put too much stock in the results of you IR temp gun analysis of the panel. There would only be arcing at a given circuit if there is juice running through it, and if your inspections are like most of mine, there generally isn't much load on the electrical branch circuits during the inspection. I have seen Zinsco panels that looked completely normal, but when the breakers were removed, there was significant arcing on MOST of the breaker contacts on the bus bars.
