Re: [DIY] Circuit breaker boxes

 

I have a rule set in stone. ALWAYS use copper. Aluminum is IMHO unsafe. It Heats, even at rated load, and below.

Square D is often more expensive. The less expensive boxes usually have an aluminum buss- this is what the breakers connect to. As long as the integrity of the box is good- no moisture is getting into it- and you are not overloading the breakers, this may work. The higher priced boxes probably have a copper buss, which is capable of carrying more current for the same thickness of metal, shich SHOULD mean a safer installation. Square D also offers two types of breakers, Homeline and QO. QO is made to a higher standard than the Homeline, which is designed to be "competitive" with the other brands. The breakers are not interchangeable.
