I am trying to find out before I buy if the milbank u2272-rl-5t9-el can be used on a 100amp residential home although it says 125amp? The new standard for meter boxes is the bypass switch. I found the rest of the accessories for this meter box except for the conduit and the hub that attaches to the conduit & the meter box. I dont know if the meter box can handle a wider conduit (5") & if so what size hub? I'm new to this so please bare with me.
