I’d like to be able to utilize 100 amps of power (50 on each leg) when plugged into 50 amp service. 1 leg will feed through multiplus and power half the panel. The other leg will feed directly to other half of panel. Can I simply splice off of neutral and ground coming into RV from 50 amp service and route 1 neutral/ground pair to multiplus with line 1, and the other neutral/ground pair to panel with line 2? Thanks!
