Bussmann BK/CBC-10 – Frequently Asked Questions

1) Can I use the Bussmann BKCBC circuit breaker on a 12-volt RV or truck system?
Yes. The BKCBC is rated 14 Vdc, which is the standard nominal rating for 12-volt automotive, RV, truck and marine charging systems running at roughly 13.8 to 14.4 volts while the alternator is charging. It is a DC-only device, so do not put it on 24-volt equipment or on any AC branch circuit.
2) What amp ratings does the Bussmann BKCBC breaker come in?
The BKCBC family runs from 10A up to 50A. The two ordering points are the 10-amp BK/CBC-10 and the 50-amp BK/CBC-50B. Size the breaker to the wire and the load, not to the appliance's peak draw alone, since a Type I breaker cycles rather than staying open.
3) How does the BKCBC terminate - do I need ring terminals?
Termination is by #10-32 TPI stud, so the cables land on ring terminals sized for a #10 stud, secured with the stud nuts. There are no blade or push-on connections. The threaded stud is what keeps the joint tight under vibration in a truck or boat, but it also means you crimp and torque ring lugs rather than plugging in a spade.
4) What does Type I mean on this Bussmann automotive breaker, and will it reset itself?
Type I is the auto-reset style: the bimetal element opens on overcurrent and closes again once it cools, so the circuit cycles on and off while the fault is still present. That is what you want on a circuit you cannot afford to leave dead and cannot easily reach, and it is the opposite of a Type III manual-reset breaker with a push button. The BKCBC is built as an automotive, Type I, heavy duty device.
5) Is a 1.5 kAIC interrupt rating enough for a circuit fed straight off a battery?
1.5 kAIC is the fault current the BKCBC can safely interrupt. That covers branch and accessory circuits downstream of a main fuse or distribution block. It is not a main battery protection device: a large lead-acid or lithium bank can deliver fault currents well above that, so the main positive run off the battery should carry a high-interrupt fuse, with the BKCBC protecting the branches behind it.
6) Should I use a resettable breaker like the BKCBC instead of an automotive blade fuse?
Use the breaker where a blown fuse means a service call or a stranded vehicle. On lighting, pumps, winches and accessory circuits in RVs, trucks and marine systems, a resettable device clears a nuisance trip without anyone carrying spares. Stick with a blade fuse where the circuit is easy to reach, where you want a permanent open on a real fault, or where the spec calls for a specific fuse class.
7) Will the BKCBC hold up to vibration and heat in a mobile install?
It is built as a heavy-duty automotive Type I device for exactly that duty, and the #10-32 threaded stud terminals are a mechanical joint that does not shake loose the way a push-on connector can. Mount it where it is accessible and keep the lug nuts torqued at service intervals.
