I'm installing my own whole-house surge suppressor and need to pick up a GE breaker
The store shows two, a 1 inch THQL 2120 and a 2 inch THQP 220.
Are both rated 220v or is the 2120 not
Thanks for your guidance

Hello jag, I’m Newf from the Home Depot’s how-to Community. Thank you for your question.
For newer panels, these breakers are interchangeable. There are some older panels where the smaller THQL breakers may not work. Both are rated for 240 volts. The smaller breakers save space, and in some cases there is a cost difference.
I hope this helps,
