Hi,

I'm replacing a JDA36250 breaker and reducing it to a 200 amp breaker.

Can anyone confirm if this is the correct replacement? I assume all JDAs will be compatible.

JDA36200 Square D 200 Amp Breaker

Thank you in advance,
David

Well yeah, based on those part numbers the two are the same except one is 250A and the other is 200A. Have you verified the AIC rating is sufficient?
 
Haven’t looked it up, but usually the frame size is different when you go from 200 to 250. Will the buss and the space you have allow for a bigger breaker?
