Bussmann CBC-10B – Frequently Asked Questions

1) What size ring terminals do I need for a Bussmann CBC-B breaker?
Both terminals are #10-32 TPI studs, so ring terminals with a #10 hole land directly on them. Torque the nuts down on the ring and you get a vibration-resistant connection, which is why stud-style breakers are used in vehicle and marine wiring instead of push-on blade types.
2) Does a Type I automotive breaker reset itself, and is that what I want for an accessory circuit?
Type I is the auto-reset configuration: it opens on overcurrent and closes again once it cools, cycling as long as the fault is present. That suits accessories where you do not want a permanent shutdown from a momentary overload, like a wiper or blower motor. If you want the circuit to stay open until someone intervenes, a Type I breaker is the wrong choice and you should specify a manual-reset or modified-reset type instead.
3) Can I mount a Bussmann CBC-B breaker in an engine bay or on an open boat console?
Yes. The CBC-B housing is waterproof, which is what makes it usable in engine compartments, marine installs and off-road vehicle wiring where splash and weather reach the breaker. It still needs the stud nuts properly tightened, since the seal is at the housing, not the terminations.
4) What amp ratings does the Bussmann CBC-B series come in?
Nine ratings from 8A to 50A: 8, 10, 15, 20, 25, 30, 35, 40 and 50 amps, ordered as CBC-8B through CBC-50B. Size to the wire and the continuous load, not to the peak draw of the accessory.
5) Is 1.5 kAIC enough interrupt rating for a breaker sitting near the battery?
The CBC-B is rated 1.5 kAIC at 14 Vdc. That is the fault current it can safely break. A large AGM or lithium bank close-coupled with short heavy cable can push fault current above that, so for main battery protection use a properly rated battery-terminal fuse and keep the CBC-B on the branch and accessory circuits downstream.
6) Should I use a CBC-B breaker or just a blade fuse for an aftermarket accessory?
A blade fuse is one-time: it blows and someone has to carry a spare and get to the fuse block. The CBC-B is a Type I auto-reset breaker, so a nuisance overload clears itself once it cools and the circuit comes back. For hard-to-reach locations, motor loads that surge, or wet installs where you do not want to open a panel, the breaker earns its place. For a simple, accessible low-draw circuit, a fuse is the cheaper and smaller answer.
7) Which Bussmann part number do I order for a 30 amp waterproof stud breaker?
CBC-30B is the 30 amp version of the waterproof stud-terminal CBC-B breaker. The series follows the same pattern throughout, so 20 amp is CBC-20B and 40 amp is CBC-40B.
8) How heavy is a Bussmann CBC-B breaker for shipping or panel layout?
Each CBC-B breaker is listed at .5 lb. Light enough to support on the stud connections in most fuse block and panel mounts, though on high-vibration equipment it is still good practice to secure the body rather than let it hang on the cable.
