B-LINE CHB280 – Frequently Asked Questions
1) Will the B-Line CHB280 breaker fit an Eaton CH loadcenter?
The CHB280 is a Type CHB breaker built for CH loadcenters. It will not seat in a BR, Homeline, or QO panel, since those use different bus stab geometry. Check the panel label for CH before ordering.
2) Is the CHB280 a two-pole 240V breaker?
Yes, it is a two-pole breaker rated 120/240V, so it lands on both legs and takes two spaces in the panel. That is the configuration for a 240V load such as a subpanel feeder, range, or large HVAC circuit.
3) What wire size can I land in an 80 amp CHB breaker?
The lugs on the CHB280 accept #4 through 1/0 AWG. At its 80A rating that covers the usual copper and aluminum feeder sizes for an 80 amp circuit, so you can terminate directly without a splice or reducer.
4) What part number do I order for an 80 amp two-pole CH breaker?
Order CHB280. The number reads directly: CHB series, 2 pole, 80 amps. There are no finish or option choices to specify on it.
5) Can I use the CHB280 as a subpanel feeder breaker?
Yes. Two poles, 80 amps at 120/240V, and lugs taking #4 to 1/0 AWG make it a common main-lug subpanel feed device in a CH loadcenter. Size the feeder conductors to the 80 amp rating and confirm the downstream panel bus is rated at least that.
6) How much space does the CHB280 breaker take up?
Physical size is 5.8 by 3.6 by 1.4 inches and it weighs about .45 lb. That is the footprint to allow for when laying out gutter space or checking clearance in a loaded CH panel.
