B-Line Spring Cage Connection Single Level-Ground Blocks

The XBPT16PE takes one conductor per clamp: #24-4 AWG on one side and #16-4 AWG on the other, with 4 AWG (16 mm2) the largest wire it will take. So it covers everything from fine control wiring up to a 4 AWG ground conductor in the same block, but it is a single-conductor-per-clamp part, not a dual-wire terminal.

It's a ground block. The green/yellow body is the standard protective earth colour convention, and it's a single level spring cage connection block, meaning the ground path is made through the rail rather than being an isolated feed-through circuit. If you need an isolated conductor path, you want a grey feed-through block from the same IEC-XB series instead.

90A under IEC ratings. Pair that with the 4 AWG maximum conductor and it suits panel ground bonding on feeder-sized circuits, not just control wiring.

No. The XBPT16PE uses a spring cage clamp, so the conductor is held by spring pressure once inserted. There is no screw to torque and nothing to re-torque after thermal cycling, which is the main reason panel builders choose spring cage over screw-type on ground blocks.

25 blocks per pack. Worth knowing before you order for a single panel job, since you're buying the full quantity rather than individual pieces.

Yes. It's part of Eaton B-Line's IEC-XB series single level range, so it shares the series rail mounting and stacks in line with the other XB blocks in a panel. That's how you build a mixed strip of feed-through and ground terminals on one rail.

XBPT16PE is the manufacturer part number, from the Eaton B-Line IEC-XB series. That's the 16 mm2 (4 AWG) spring cage protective earth block in green/yellow.
