1 x Main 400A 4P MCCB; 3 x 125A 4P C curve MCB + ELR for 125A sockets; 3 x 63A 4P C curve MCB + ELR for 63A sockets; 6 x 32A 4P C curve MCB for 32A 5P sockets; 6 x 32A/30mA DPN RCBO for 32A 3P sockets; 6 x 16A/30mA DPN RCBO for 16A sockets. What makes the three phase 400A configuration particularly relevant? This capacity level sits in the medium-to-large industrial range, suitable for factories, warehouses, and commercial facilities with substantial electrical loads. It's neither too small (like residential 100-200A panels) nor too. Units are available in 100A, 225A, and 400A as well as up to 600V maximum rating. This unit is Plug-in unit tap box that is rated at 400A. All busway rating are listed to UL. The service size is 400A. Ultimately, I want the shop to have a 150A load center (sub panel), and the main house to have two, 200 A load center (sub panels). Inside the equipment building, immediately after the meter socket, I am assuming would need a 400A fused disconnect, followed by a 600A.
