Hello,

I need to add a 20 amp breaker to this panel for a heater. Can someone tell me if this panel will accept QO or Homeline breakers? Thanks!!!

QO breakers are 3/4" per pole and have the little red trip indicator window next to the word OFF. Homeline breakers are 1" per pole, with no trip indicator.

Looks like QO.

Cheers, Wayne

Looks like QO to me also. As Wwhitney said the "trip window" is almost a signature of the QO panel.

"Almost" You will find them on Eaton type CH (former Cutler-Hammer) too, think the patent has expired although early SQ D QO/QOB circuit breakers did not have the Visitrip feature, BTW, QOB is the bolt-on version QO is the plug-in version.
