Fusible Switch Busway Plugs Fusible switches in all busway fittings (plugs, power takeoffs, and reducers) have the following short-circuit ratings when used with the fuses shown. To qualify for R fuse rating, switches must have R fuse clips which reject other type fuses. The interrupting rating of the fuse must equal or exceed the short-circuit rating of the switch. It is lower than the short-circuit rating of the switch, then the combination has the rating of the fuse.
