[QUOTE="Evans Electric, post: 466985, member: 1408"] I know what you mean , and strangely I've never considered this particular scenario before . I'm just of , say , hospital complexes I've worked on .... there would be possibly a 500A PME incomer , then loads of separate buildings with various sized sub-mains to them but , as I remember them , the bonding matched the sub-main supply characteristics , not whatever a 500A would be . Phoenix just to recap , the site supply is 200A PME..... a BBC with a load of sw/fuses on it ....... the one to this Heavy Plant workshop is via 100A Henley fuses , a sw/fuse and 40m of 50 / 70mm SWA imperial from the late 1960's . I have to say I've never come across bonding cables going back to a remote switch room . [/QUOTE]
