B-LINE BQL3100 – Frequently Asked Questions
1) Is the B-Line BQL3100 a bolt-on or plug-in breaker?
The BQL3100 is a bolt-on breaker, so it mounts to the panel's bus with screws rather than snapping onto a stab. If your panelboard interior is prepped for plug-in breakers, this one won't seat. Bolt-on and plug-in are not interchangeable in the same mounting position, so confirm your interior is the bolt-on style before ordering.
2) What wire size can I land in the 100A BQL three-pole breaker, and can I use aluminum?
Lugs accept #8 through 2/0 AWG and are rated Cu/Al, so either copper or aluminum conductors can be terminated. That range covers typical 100 amp feeder sizing in either metal, and it means you don't need a separate aluminum-rated lug kit.
3) Can I use this three-pole 100A breaker on a 480V system?
No. The voltage rating is 120/240 V, which makes it a breaker for single-phase 120/240 V or 120/240 V three-wire panel applications only. For 480Y/277 V or 480 V delta distribution you need a breaker rated for that system voltage; installing a 240 V class device on 480 V is a hazard, not a derate.
4) I need to replace an existing BQL breaker in a load center. Is this the same type?
Yes, this is a BQL type breaker, sold as a classic replacement device, so it goes back into panelboards prepped for bolt-on BQL breakers. Match the pole count and amperage as well: this one is three-pole, 100 A. Order it as B-Line model BQL3100.
5) Is this breaker approved for feeding rooftop HVAC and refrigeration equipment?
It is HACR Rated, which is the marking required when a breaker supplies heating, air conditioning and refrigeration equipment whose nameplate calls for an HACR type breaker. At 100 A three-pole it suits a packaged unit or condenser feeder within the 120/240 V rating.
6) Can I use this three-pole breaker as a two-pole by leaving one pole unused?
No. All three poles of the BQL3100 are mechanically tied and trip together, and leaving a pole unconnected is not a listed use. For a 240 V two-wire load, order the two-pole BQL in the amperage you need instead of derating this one.
7) How much space does the BQL3100 take up in the panel?
The breaker body measures 3 x 5 x 3 inches (height, length/depth, width) and weighs about half a pound. Use the 5 inch depth figure when checking clearance to the panel cover and the gutter space behind the trim.
