Bussmann BP/S-12 – Frequently Asked Questions
1) Will a Bussmann BP/S plug fuse screw into my existing Edison-base fuse panel?
Not directly. The BP/S is a rejection-base (Type S) fuse, so it only threads into a Type S adapter, not a bare Edison socket. In an older screw-in panel you install the matching Type S adapter into the socket first, then thread the fuse in. Once the adapter is in, it locks the circuit to that amperage so nobody can drop in an oversized fuse later.
2) What amperages does the Bussmann BP/S time-delay plug fuse come in?
Four ratings: 6-1/4A, 8A, 12A and 15A, ordered as BP/S-6-1/4, BP/S-8, BP/S-12 and BP/S-15. All are 125V. Pick the amperage to match the branch circuit's conductor size, and remember the Type S adapter has to match the fuse rating or it will not accept the fuse.
3) Can I use a 125V plug fuse on a 240V circuit like a water heater or range?
No. The BP/S is rated 125V, which covers 120V line-to-neutral branch circuits only. A 240V two-pole load needs a cartridge-type fuse rated for that voltage, not a screw-in plug fuse. Keep the BP/S to lighting and receptacle circuits in a residential load center.
4) My fuse keeps blowing when the furnace or a motor starts up. Will a time-delay fuse fix that?
That's exactly what the time-delay element is for. The BP/S rides through the brief inrush a motor, compressor or furnace blower draws at startup instead of opening on it, while still clearing a sustained overload. A fast-acting plug fuse of the same amperage will nuisance-blow on those loads. It is not a licence to go up in amperage, though: keep the rating matched to the wire.
5) Why would a property manager choose rejection-base fuses over standard plug fuses for rental units?
Tamper control. A standard Edison socket will accept any amperage someone cares to screw in, which is how a 15A circuit ends up with a 30A fuse in it. The BP/S rejection base will only enter the Type S adapter sized for it, so once you have adapted a panel the circuit is locked to its correct rating. For a landlord maintaining older fused panels across multiple units, that removes the most common unsafe field substitution.
6) How are Bussmann BP/S fuses packaged for counter stock?
They come on a blister pack, which suits retail pegboard and service-counter stock. The base is heavy-duty plastic, so they hold up to handling and repeated panel service.
