Milbank K4528 – Frequently Asked Questions

1) What wire sizes will the Milbank 200A metering block assembly accept?
The Milbank 200A block assembly takes conductors from 6 AWG up to 350 kcmil in its lay-in lugs. That range covers a 200 amp service entrance run in copper or aluminum, so a typical 2/0 copper or 4/0 aluminum feeder lands well inside it. Two terminals per block.
2) What is the difference between Milbank K4527, K4528, K4529 and K4530 blocks?
They are the same 200A, 600V AC block in four lug configurations. K4527 is internal hex, K4528 is external hex, K4529 is internal hex horn, and K4530 is external hex horn. Internal versus external hex is the drive on the lug setscrew, which decides what tool the electrician needs at the socket. The horn versions carry the horn bypass style terminal. Pick the one that matches the block you are pulling out of the meter socket.
3) How do I know which Milbank replacement block matches my meter socket?
Match the lug drive and the terminal style on the block you are removing. Look at the setscrew: an internal hex takes an Allen key in the socket head, an external hex takes a wrench or socket on the head. Then check whether the existing block has horns. Internal hex is K4527, external hex is K4528, internal hex with horn is K4529, external hex with horn is K4530. All four are 200A and take 6 AWG to 350 kcmil, so the electrical side is the same across the set; the mechanical match is what you are choosing.
4) Can I use a Milbank 200A block assembly on a 480V system?
Yes, within limits. The block is rated 600 volts AC, so 480Y/277 and 240/120 distribution are both inside its rating. Anything above 600V AC is out. The current limit is the harder constraint at 200 amperes; do not put it on a 400A service.
5) How does the Milbank 200A block mount, and do I need to recess it?
Surface mount. The block fastens to the panel or enclosure face, so there is no recessed pocket or back-box prep needed behind it. That is what lets it drop into an existing socket interior on a retrofit.
6) Will a 200A Milbank lay-in lug block work for a multi-tenant apartment metering stack?
For individual 200A tenant positions, yes. Each block handles one metering point at up to 200 amperes and 600V AC, and the lay-in lug design lets you drop the tenant feeder in rather than threading it through a closed barrel, which matters when you are working in a crowded gutter. For a property manager standardizing across a building, note the lug drive style varies by model, so confirm whether your stack uses internal or external hex before buying a quantity.
7) Are Milbank K4527 through K4530 blocks sold individually or in a multi-pack?
Each is a single block, one per kit. For a two-position or multi-gang metering installation you order one per meter position you are repairing, and each block carries two terminals.
