I ordered a QO 3030 Quad today, then I went on the web to see what it will look like and I couldn't find any. Now I am afraid they don't exist and the guy at the parts house probably ordered me a Homeline. Has anyone seen a QO 3030 quad??

I have never seen a QO "Quad" ever. Only have ever seen QO "tandem" type.

They don’t make any quad QO breakers. There is a kit for older NON-CTL load centers that has (1) QO2030, (1) QO3020 and (1) handle tie for the center 30 amp breakers. I believe the catalog number is QO20303020.

A Square D QO3030 is a tandem 30A single pole non-CTL breaker, which mounts in a single width space.

Be aware, the QO20303020 (actually all Square D tandems) should not be used on circuits which require a 2-pole common trip breaker.

I saw in a new modular home, in a qo panel, a 2 pole tandem breaker. The main 2 pole was 30a, and the piggy backs were 15 amps. I have never seen this before, and didnt get the parts #'s off of it.
