B-LINE BQL290 – Frequently Asked Questions
1) Will the B-Line BQL290 breaker land my #2 AWG aluminum feeder?
The BQL290 accepts #8 through 2/0 AWG copper or aluminum conductors, so a #2 AWG aluminum feeder lands directly in the lug. That range also covers 2/0 copper at the top end, which is what most 90 amp two-pole feeders to a subpanel or a large motor load will use.
2) Is the BQL290 a 90 amp two-pole breaker, and what voltage is it rated for?
Yes. The BQL290 is a two-pole, 90 amp thermal magnetic breaker rated 120/240 V, meaning it serves a single 240 V load or a 120/240 V feeder using both hot legs and neutral. It is not a 480 V or three-phase device.
3) Can I use the BQL290 to feed an air conditioner or heat pump?
It is HACR rated, so it can be used as the branch circuit protective device for heating, air conditioning and refrigeration equipment where the nameplate calls for an HACR type breaker. At 90 amps two-pole it suits larger condensing units and air handlers with electric heat.
4) Is BQL290 the same thing as an Eaton BAB breaker?
The BQL290 is the B-Line catalogue number for an Eaton BAB thermal magnetic circuit breaker, a classic replacement breaker. Order by BQL290 and you get the BAB-style device; the MPN on the part is BQL290.
5) What size opening does a BQL290 need in the panel?
The breaker measures 5 inches deep, 3 inches wide and 2 inches high, and weighs half a pound. Check that against the gutter depth and the two-pole space you are filling before you pull the deadfront.
6) Is the BQL290 a GFCI or AFCI breaker?
No. It is a thermal magnetic breaker only, providing overload and short circuit protection. There is no ground fault or arc fault sensing built in, so where code requires GFCI or AFCI protection on the circuit you will need a protective device of that type or a downstream GFCI.
