B-LINE BQL240 – Frequently Asked Questions
1) Is the Eaton BQL240 breaker a bolt-on or a plug-in type?
The BQL240 is a bolt-on breaker, which means it fastens to the panel bus with a screw rather than clipping on. Bolt-on and plug-in breakers are not interchangeable in the same panel, so confirm your loadcenter or panelboard is set up for bolt-on mounting before you order. It is a two-pole, 40A device rated 120/240V.
2) What size wire can I land on the Eaton BQL240 40 amp breaker?
The lugs take #14 through #8 AWG, and they are rated for both copper and aluminum conductors. For a 40A two-pole circuit that typically puts you on #8 copper, and the dual-rated lug means you do not need a separate connector if the feeder is aluminum.
3) Can I use the BQL240 two-pole breaker for a 240V appliance circuit like a dryer or water heater?
Yes. Being two-pole at 40A and rated 120/240V, it lands across both legs and supplies a 240V load. A 40A two-pole is the common size for an electric water heater or a range feed, and the #14-8 AWG lug range covers the conductor you would run for it.
4) What part number do I order for the 40 amp two-pole BQL bolt-on breaker?
Order catalog number BQL240 from Eaton's B-Line BQL bolt-on classic replacement line. The 240 in the number reads as two-pole, 40 amp.
5) Will the BQL240 work in a 208Y/120 three-phase panel?
It is rated 120/240 Vac only, so it is a single-phase device. For a two-pole circuit off a 208Y/120 three-phase panelboard you need a breaker carrying a 240 Vac or 120/240 slash rating appropriate to that system, and this one should not be substituted in on the assumption that the poles are the same.
