Square D Type QO 40A Tandem?
|
|
|
Hi all,
I'm wondering if Square D Type QO Breakers come in tandem form (skinny taking up 1 slot only) for 30 & 40A. I can't seem to find them. I do find tandems in 15 & 20A though.
Reason : Installing arc-fault in a panel filled with all tandems (15/20), there is no more room. There are 3 double pole breakers each which take up 2 spaces. They are 40, 40, 30A.
So I'm not adding additional circuits, just arc-faults don't come in tandem. I'm trying to replace a 40, 40 or 30 with a skinny tandem and free up some room...otherwise replace panel.
Much appreciated.

Forgot to mention, I'm only installing 1 arc-fault breaker, which is creating this space issue.

I have never seen them over 20a. You are going to end up with a panel change or a sub panel IMHO.

That's not something that I have seen. You may want to check Schneider website; or contact a local supply house that is a Sq D distributor. Not a 'big box' store, but a supply house.

Double pole breakers can't replaced by tandems.
The double poles pick up both legs.
Tandems don't.
2 of them side by side won't be any help either. Handle ties won't fix the issue of the common trip requirement.
