Here we go:
Situation: 2story farm house with attic knob and tube wiring used. Owner has wiring issue's on second floor and the wiring needs replaced.
Solution: I have been asked if this is ok and just need some reassurance from you guys. They want to add a MLO subpanel in the attic to be used to supply all 2nd floor lights and outlets. Now I know this will be handled as a feeder. All non-continuous loads so feeder sized to 100% of load. Should be a 4-wire feed from the service panel to the sub keeping grounded and equipment grounding conductor separate. They are not sure of subpanel size I suggested 60amp. Easiest route from main service to attic would be outside wall. Can they run SER cable along the outside wall to gain access to attic? I know they will need 4conductor ser cable 3insulated conductors and one bare for egc. Your thoughts?
