B-LINE BQL30 – Frequently Asked Questions
1) Is the B-Line BQL30 a bolt-on breaker or a plug-in breaker?
Bolt-on. The BQL30 is a BQL-type bolt-on breaker, so it fastens to the panel bus with a screw rather than clipping on. A plug-in breaker will not substitute in a bolt-on panel and vice versa, so match the mounting style in the panelboard before ordering.
2) What wire sizes will the BQL30 breaker lug accept, and can I land aluminum conductors?
The lug takes #14 through #8 AWG and is rated Cu/Al, so both copper and aluminum conductors are acceptable. For a 30 amp circuit that covers the usual #10 copper as well as the larger aluminum sizes electricians use to make up the same ampacity.
3) Can I use this 30A single-pole breaker on a 240V circuit like a water heater?
Not by itself. The BQL30 is single-pole, so it lands on one hot leg and serves 120V branch circuits. Its rating is 10 kAIC at 120/240 Vac, meaning it is suitable for use in a 120/240V system, but a 240V two-wire load such as a water heater needs a two-pole 30A breaker.
4) Can this breaker feed an air conditioner or heat pump circuit?
It is HACR rated, so the BQL30 is acceptable for use as the branch circuit device on heating, air conditioning and refrigeration equipment where HACR is called for on the nameplate. Confirm the equipment nameplate maximum overcurrent device is 30 amps or higher.
5) I need to swap out a failed 30 amp breaker in an older BQL panel. Is this the right replacement?
That is exactly what the BQL30 is built for. It is a classic replacement circuit breaker in the BQL family, bolt-on, single-pole, 30 amps, 10 kAIC at 120/240 Vac. Match the existing breaker on type (BQL), poles, amperage and mounting style, and confirm the interrupting rating is equal to or greater than what the panel schedule calls for.
6) How much space does a BQL30 take up in the panel?
The breaker measures 5 inches deep, 3 inches wide and 1 inch high, and weighs half a pound. The 1 inch dimension is what matters for space planning, since it corresponds to a single pole position in the panelboard.
7) What is the manufacturer part number for the 30 amp single-pole B-Line BQL breaker?
BQL30, from B-Line. That covers the bolt-on, single-pole, 30 amp version with the #14-8 AWG Cu/Al lug and 10 kAIC at 120/240 Vac rating.
