I have a situation where a friend of mine wants to add what he calls a "critical load sub panel" which will be fed by a battery back-up system via his solar company. They are bringing over a battery back up set up which they say is rated at 40 amps @ 120V. I need to bring six existing circuits into the new "critical load sub panel". Three of the existing circuits originate from the meter/main/load service panel and the other three existing circuits come from a different sub panel. I have two questions: Am I allowed to splice inside the service panel and the sub panel to extend these six circuits to the new "critical load sub panel"? And if so, is there a particular type of connector that needs to be used for the splicing? Also, the fact that the "critical load sub panel" is fed at 120V can I install a jumper between to two critical load sub panel input lugs so I have 120V on both legs of the busbar? Or is there a specific type of sub panel unit to be used in this situation that is only fed with 120V? Any input on all of this would be greatly appreciated.
