Milbank Z904304-AO – Frequently Asked Questions

1) What wire sizes will the Milbank Z904304-AO top connector accept?
The Z904304-AO top connector takes a single conductor anywhere from 3/0 AWG up to 750 kcmil. It's a one-conductor mechanical lug, so each phase needs its own connector, and the 75 degree C terminal rating is what you size your conductor ampacity against.
2) Which Milbank metering enclosures does this 750 kcmil top connector fit?
It's built for Milbank S1855 and S1856 metering systems. The mounting is plug-in, so it drops into the connector position in those units rather than being bolted up as a loose lug. If your gear is a different Milbank series, this isn't the connector for it.
3) Do I need one Milbank Z904304-AO per phase or does one cover the whole service?
One per conductor. The Z904304-AO is a single-conductor mechanical lug, so a three-phase service means three of them, plus whatever the neutral position calls for. Order quantity accordingly rather than assuming a set.
4) Is the Milbank top connector rated for a 600V commercial service?
Yes, it's rated up to 600 volts AC and is UL Listed, which covers typical 120/240V, 120/208V and 277/480V utility services. It carries no insulation of its own, so it relies on the enclosure for isolation and cover clearance.
5) How much room does the Milbank Z904304-AO connector need inside the gutter?
Overall size is 10.5 x 7.12 x 10.5 inches. That's a substantial block, so when you're planning wire bending space for 750 kcmil in the top section of an S1855 or S1856, budget for it before you pull conductors.
6) Is this a compression lug or a set-screw type connector?
Mechanical, not compression. You land the conductor and torque the setscrew, no hydraulic crimp tool or dies needed, which is why it's common on utility metering work where field changes happen.
