Thank you for your question. The R208CR2A is rated for service entrance and includes a 200a main breaker. Please check with your local authority having jurisdiction to determine if the R208CR2A ringless 200a main breaker is approved for your application.
Yes, it can be fed from the top or bottom. Get the 4 bolt water tight threaded coupling that fits the mast. It comes with a 200A main breaker It has 8 positions so it will accommodate 8 110V circuits or up to 4 220V circuits.
Greetings Marky, My name is Tom, also known as HD116 at Home Depot's How to Community. I am here today assisting with some questions that have gone unanswered and saw yours. This outlet box is designed for temporary use, requires a meter, and has 8 traditional size spaces for breakers. It can accommodate any combination of breaker configurations that can fit in 8 spaces and it can power up to 200 amps. Sorry for the delay and hope that helps.
