Beside double tap, copper and aluminum together, and 2 differant gages of wires what else is there to say about this. This was coming off the main disconnect to a 50 AMP subpanel for electric dryer. The 100 AMP Bulldog Pushmatic panel was full. I remember hearing about the Bulldog panels before, were they problamatic or just a bad design?? Yes I saw the double tap on upper left. Thanks.

Paul,

The breakers are bad about the switches popping loose.

Seems like I only come across them only on condos that were constructed late 60's early 70's.

Bulldog panels and breakers are a good design but they are getting pretty old. I would say that that the youngest will be around 30-35 or so years old. As they are this old replacement breakers can be on the expensive side. I have only seen a the "button" off on one breaker, not much different than broken breaker handles, IMO.

I would let my client know that the panel and breakers are old, replacement parts may be expensive and hard to find as time goes on. I would then let them know that the average life expectancy of an electrical panel/breaker is around 40 or so years of age.

I would hate to be the person relying on the green color code to indicate ground at the other end of this wire.

What makes you think that you see aluminum wire? With that type of insulation, I think you're looking at tinned copper.

Just because you can't find something on the market today does not mean it's automatically bad. I am not aware of any problems specific to Bulldog breakers.

The double tap is a concern.

I believe that he is talking about the stranded aluminum SE cable. This is not tinned copper.

I don't disagree in concept, otherwise most of us would be automatically bad, though astronomically expensive replacement parts are available even in our case.

As far as the Bulldog breakers themselves my comments would echo Scott's concern that they are nearing or beyond their statistical lifespan. That comment would be in my report.

*IF* we go with the assumption that those are tinned copper, then a more important problem arises.

That of "rubber insulation".

If those 'are' tinned copper, then the insulation will be "rubber", and rubber insulation dries out, becomes brittle and cracks, leaving a compromised insulation (at best) and a failed insulation (at worst).

The solution then it to replace the conductors. Before replacing the conductor, the insulation should be verified and, if rubber, the insulation checked with a megger. The insulation will likely fail that test (if rubber) and the conductors will need to be replaced anyway, now having spent more money than would have been spent to have just gone ahead and replaced the conductors to start with.

By the size of the strands in those conductors, I'm inclined to agree with John - that they may likely be tinned copper ... however, that brings up the other problem I stated above.

I.e., "tinned copper" is 'not a good thing' to find, and when you find tinned copper, give the conductor insulation a good looking over. If the conductors are stiff (smaller conductors such as #12, etc.), then the insulation had dried and hardened, being in need of replacement.
