If 210.4 B says that all multwire branch circuits must have a disconnect means so that all their ungrounded conductors simultaneously disconnect
And if 210.4 c says that a a MWBC may only supply line tonneutral loads then why does
210.4 c exception 2 say that a MWBC multi wire branch circuit may supply line to line loads only if all ungrounded conductors are disconnected simultaneously
This last exemption makes 210.c invalid (can only supply line to neutral loads) because MWBS must always have their ungrounded conductor disconnected simultaneously
