In a large bunkhouse we need to add a second range, water heater, and kitchen outlets. The existing panel is 125 AMP (with breaker), and don't want to redo entire panel. A consultant said to install a 200 AMP drop, with a panel to handle the additional load. Would you then feed each of the panels from that drop as main panels, or use a new 200 AMP panel as the main, and the 125 as a sub-panel from that? I assume in either instance, the grounding would be done as a 200 AMP service. Just realized if each was a main panel, the new one couldn't exceed 75 Amps, or total would be over 200. Any other ideas appreciated.
