0 Pietpower Posted October 5, 2020 Share Posted October 5, 2020 I am no electrical expert. Would also like to hear what other say. I don't think there is any limit on the number of sub db boards as long as you have breakers cascading. Iow the breaker in the sub db must trip before the breaker in the main board trips. And if I remember correctly this is not the Amp rating of the breaker but the kA fault current rating. Quote Link to comment Share on other sites More sharing options...
