To respond to the Siemens answer. No, I have two single pole breakers that are both connected to a transfer switch. I want to know if I can use the whole house surge protector breaker to replace those two single-pole breakers. Or do I have to use breakers that are not connected to a transfer switch?
No, this cannot be done. Firstly, there is no handle tie available to make a common disconnect and, secondly, doing so would not make the poles common trip. Each pole services one leg of the load center and one 120V circuit. It is important that the poles operate independently so that if one fails there is still protection provided on the other leg.
We cannot advise. Please check with Schneider Electric for guidance on which breaker types are UL approved for your Square-D panel.
If the LEDs are on at all (regardless of the intensity) then there is no reason to be believe surge protection is not being provided. However, we don't know the condition without examining the device. If you are concerned about the life expectancy our recommendation is to replace it. There is no benefit to installing both the old and new device together. Doing so will not increase the level of protection.
No
Yes, MSA2020SPDP has a discharge current withstand rating of 10kA line-to-neutral (not to be confused with the 10kA interrupting rating).This is listed on page 3-16 of the link below. https://w3.usa.siemens.com/powerdistribution/us/en/speedfax-product-catalog/Documents/2017/SF-17-Sect-03-ALL-web.pdf
I think it will fit physically but it's not rated for a GE panel. GE makes whole house surge protector, however it doesn't have the built in breakers so you loose 2 full size spaces.DIYer
Yes. MSA2020SPDP is a Type QP breaker. The designation of circuit breaker types changed in the late 1970’s when series ratings were introduced. Before that time ITE manufactured circuit breakers that were identified as EQ-P or EQ-T. In approximately 1976 these designations were changed to circuit Breaker Types QP and QT, respectively, by dropping the E. Types QP and QT can be used in equipment that have the earlier ITE Types designated on the interior label or marking of the equipment. For a formal letter stating this send a request to productselection.us@siemens.com.
The electrical box says: "Circuit Breakers use class CTL Murray Style MP, I.T.E. style EQ-P, or Westinghouse Quicklag P" It does not say MP-T style. Will this surge protected Circuit breaker fit?
yes, 6.5 in. is wrong. This is the size of a standard 2 pole breaker.
