B-LINE BQL315 – Frequently Asked Questions
1) Is the B-Line BQL315 breaker a bolt-on or a plug-in type?
BQL315 is a bolt-on breaker. It fastens to the panel bus with screws rather than clipping on, so the panel interior has to be drilled and tapped for bolt-on mounting. If your panel bus is set up for plug-in breakers, this one will not mount.
2) What wire size can I land in a 15A B-Line BQL breaker?
The lug accepts #14 through #8 AWG, and it is rated for both copper and aluminum conductors. At 15 amps you will most often be landing #14 copper, but the lug range gives you room if the run is long enough to need upsized wire for voltage drop.
3) Can I use the BQL315 on a three-phase panel?
It is a three-pole breaker rated 120/240 Vac, so it lands on three bus phases and trips all three legs together. That suits three-phase loads on a 120/240 V system. Do not apply it above its 120/240 V rating.
4) Is this breaker rated for a rooftop AC or heat pump circuit?
Yes, the BQL is HACR rated, which is the marking required for branch circuit protection of multi-motor heating, air conditioning and refrigeration equipment. Match the 15A rating to the maximum overcurrent protection on the unit nameplate.
5) Can I land aluminum feeders on this breaker or do I need copper?
Either. The terminals are Cu/Al rated across #14 to #8 AWG, so aluminum branch conductors are acceptable without a separate adapter lug. Use the correct torque and an approved antioxidant practice for aluminum.
6) How much space does a three-pole BQL breaker take in the panel?
The breaker measures 3 in high, 3 in wide and 5 in deep, and weighs half a pound. Three-pole devices occupy three spaces in the panel interior, so plan for three consecutive bolt-on positions across all phases.
