I just recently purchased a tri-plex and i want to put the washer and dryer load on the electricial panel that the landlord pays the hydro. Right now there is 3 meters and the service feeds one 100amp panel in the basement suppling one unit. Beside it are 2 100amp fused disconnect switches one feeds Unit 2 and the other feeds Unit 3 both are 100amp panels also. My question is can i add a 60amp sub panel from one of the 100amp fuse disconnects to supply the laundry load. This panel would also fed Unit 2 100amp panel. Or can i run two feeds off the 100amp disconnect switch one feeding the 60amp panel and one feeding the 100amp panel in Unit 2
