In my process of adding an EV charging station I had wanted to add another 20 amp 220V outlet for occasional use of other 220V equipment in the garage. (band saw, radial arm saw, non business CNC machine, etc) With the 50 amp breaker for the charging station the sub panel is now full. They make high density breakers (4 poles in the space of 2), but I was unable to find one for this panel.
I know the odds of one of you being specifically familiar is slim, but its worth a shot.
Before somebody says, "Did you try Home Depot?" in a dry nasally voice. Yes I tried all the usual easy suspects.
The sub panel is a GE PowerMark Gold Load Center. I am looking for a drop in 4 pole high density breaker in the configuration of 20/20-20/20. It looks like the Siemens breakers with a UNV suffix may be a correct fit, but the outside poles on the only one I found were 15 amp. All the existing circuits are 20 amp. The panel is currently being used as a sub panel, and is full at the moment. Other Siemens breakers I found that appeared to be a match will not physically fit. They have a blocker plate on the connections, and the physical gap in the middle is to narrow.
I did also look for a GE solution since its a GE panel, but was unable to find anything at all. I would ask them if they had a solution I had not found, but they make accepting all cookies and agreeing to receive SPAM a condition of contact.
The suffix UNV I found with the 15 amp poles was at Lowes. I did not physically try it, but visually it appears to have the correct gap to fit around the plastic rejection tab in the panel, the correct depth for the contact lugs, and correct snap in length when compared directly with the 50 amp GE breaker I used for the EV station.
