I'm looking at doing some upgrading / replacement of breakers to coincide with a room addition I'm doing in my house. I have a QO-16M T3 series combination service panel made by SquareD. It is currently filled to capacity with single breakers (and one tandem).
My questions are as follows:
1)Why can I not find any tandem breakers where the toggles are one on each end of the breaker? (The one that's in the panel is like this. All others that I can find are side by side mini-toggles). While I don't mind even changing out the tandem that's there if it was due to a design flaw/etc, I would like to know why they don't seem to be used.
My second question pertains to the type of tandem break I should be using. A look at Home Depot, Grainger's, or even the SquareD catalog turns up the following. Two types of breaker, absolutely identical in specification, only different in price. The QOT1515 is $38.60. The QO1515 (with a side note of: "For Use in Old Style Non-Class CTL QO Load Centers") is $48.50. A message off to Grainger's doesn't give me any useful information. Which tandem breakers should I be using?
Cheers
