Eaton CHDB330F – Frequently Asked Questions
1) What wire sizes will the Eaton CHDB power distribution block accept on the line and load sides?
The Eaton enclosed distribution block takes one line conductor from 300 kcmil down to #4 AWG, and up to twelve load conductors from #4 to #14 AWG. That lets you land a single feeder and split it into as many as 12 branch taps off one block.
2) Which amperage ratings does the Eaton CHDB enclosed distribution block come in?
Two ratings: 380 amperes, ordered as CHDB330F, and 570 amperes, ordered as CHDB377F. Pick the one that covers your feeder ampacity.
3) Is the Eaton CHDB block finger-safe and UL Listed for a code-compliant install?
Both. The block is UL Listed, and the enclosed housing is built with finger-safe features that shield the energized terminals from accidental contact while you are wiring or servicing the panel.
4) Can I use an enclosed power distribution block instead of splicing a feeder with split-bolts?
That is exactly what this Eaton block is for. Rather than field-splicing, you land one 300 kcmil to #4 AWG feeder on the line lug and terminate up to twelve #4 to #14 AWG branch conductors on the load side, all inside an enclosed, finger-safe housing. It gives you a documented, UL Listed termination point instead of taped splices buried in the gutter.
5) Is the Square D 9080LB a drop-in replacement for an Eaton CHDB block?
No. The Square D Linergy 9080LB is a 3-pole block, while the Eaton CHDB is a single-pole enclosed block with a finger-safe housing. Pole count, body width and mounting footprint differ, so the two are not interchangeable on the same panel pattern. If you are replacing an existing single-pole Eaton CHDB, stay with the CHDB - the 1.75 inch width is what the existing panel layout was laid out around.
6) My feeder is smaller than 570A - do I have to buy the 570 amp Eaton block?
No. The Eaton CHDB enclosed distribution block comes in two amperage options: the CHDB330F rated 380 amperes and the CHDB377F rated 570 amperes. Both share the enclosed finger-safe construction and UL Listed certification, so a lighter feeder can use the 380 ampere CHDB330F without giving up the safety features.
7) Where is the Eaton CHDB distribution block typically installed?
Commercial and industrial distribution panels, panelboards and load centers, switchgear, and motor control centers. The usual job is taking one feeder into a panel and breaking it out to multiple branch circuits, on retrofits as well as new construction.
