B-LINE CHP290 – Frequently Asked Questions
1) What amperage and voltage is the B-Line CHP290 breaker rated for?
The CHP290 is a two-pole 90 amp breaker rated 120/240V, so it's sized for a 240V two-pole load such as a large feeder, subpanel, or heavy appliance circuit. Both poles trip together on a fault in either leg.
2) Will the B-Line CHP290 plug into any load center?
It's a plug-in breaker for CH-style loadcenters, not a bolt-on or a universal fit. Plug-in breakers only seat on the bus stabs they were designed for, so check that the panel interior is the CH type before ordering. For a panel that takes bolt-on breakers, a plug-in device will not mount.
3) Can I use a 90 amp two-pole breaker as a main or subpanel feeder breaker?
A 90 amp two-pole device at 120/240V is a common choice for feeding a subpanel or a single large 240V load. The CHP290 will take up to 1/0 AWG copper or aluminum, which is what feeder runs at that ampacity typically call for. Whether it can serve as a main depends on your loadcenter being rated for main breaker conversion, so verify the panel's own labeling.
4) Is the CHP290 a GFCI or AFCI breaker?
No. The CHP290 is a straight thermal-magnetic overcurrent device, two-pole, 90A, 120/240V. It provides no ground fault or arc fault protection. If the circuit needs GFCI or AFCI protection, you need a breaker specifically built with that function.
