I have a 220 volt 22 amp heater that I use for a greenhouse. It gets wet when I water and I want to protect it with a GFCI circuit breaker. My current panel is a subpanel on a detached garage. I have a GE Power mark subpanel box that fits plug in circuit breakers. My wire is 10 gauge copper and I currently have a 2 pole 30 amp circuit breaker. I have looked and looked but all I can find are a 20 amp and 50 amp circuit breaker.
I can't use a 20 amp breaker because the heater is 22 amps. I can't use a 50 amp circuit breaker because my wire is too small. Therefore the only appropriate circuit breaker is a 30 amp breaker.
Question #1: Is that statement above true?
I assume it is so I will continue.
I did buy a 30 amp GE GCFI circuit breaker but it is a screw in type.
Question #2: Does a plug-in 30 amp GFCI circuit breaker exist that will fit a GE powermark plug-in style subpanel? If so, where can I get one?
I assume that is does not because I cant find it anywhere on the internet.
I could get the 50 amp breaker and run new thicker wire, but that is too much work.
Therefore I have chosen to install a subpanel solely to house my 30 amp GCFI circuit breaker and as I read about this I had some questions.
Question #3: Can I use the old 30 amp circuit breaker from the original subpanel to power the new subpanel and use 10 gauge wire to supply it if I only run the 22 amp heater off of it? Or do I need a higher amp circuit breaker and wire connecting the two subpanels?
Question #4: Do I bond the new subpanel with a green screw or not?
The original subpanel in the detached garage does not have a green bonding screw nor a grounding rod.
Question #5: Should I bond the original subpanel with a green screw and run a grounding rod or just leave it as it is.
