Milbank BL7474 – Frequently Asked Questions

1) What is the difference between Milbank BL7474 and BL7499 block assemblies?
Same 100A block assembly in two metering configurations. BL7474 is the standard block assembly; BL7499 is the horn bypass version, which gives you the bypass path used when a meter has to be pulled or changed without dropping the load. Both are 600V AC, 2-terminal, lay-in lug blocks. Pick the one that matches how the socket or enclosure is built, since they are not interchangeable in the field.
2) What size conductors will the Milbank 100A block assembly take?
The lay-in lugs accept 6 AWG through 2/0 AWG. That covers typical 100 amp copper and aluminum service conductors. If your feeder is larger than 2/0, this block will not terminate it and you need a higher-rated assembly.
3) How much room do I need inside the enclosure for this Milbank block assembly?
The block measures 5.725 x 2.758 x 2.125 inches overall, and it is a surface-mount unit, so it bolts to the back pan rather than hanging off a rail. Lay out clearance on top of that footprint for bending 2/0 conductors into the lugs.
4) Can I use this 100A block assembly on a 480V system?
Yes. The Milbank BL74 block assembly is rated 600 volts AC, so it covers 120/240V residential and light commercial work as well as 277/480V systems, as long as the load stays within 100 amps.
5) Is this a replacement part for an existing Milbank meter socket?
It is a metering accessory block assembly from the Milbank MSMC family, intended to go into metering equipment rather than to be used as a standalone junction block. Match the family code and the configuration (standard BL7474 or horn bypass BL7499) to what came out of the socket, because the block has to line up with the existing socket hardware.
6) Do lay-in lugs make this easier to wire than a setscrew barrel connector?
That is the point of the design. With lay-in lugs the conductor drops into an open channel and the pressure plate clamps down, so you are not threading a long 2/0 conductor through a closed barrel in a tight meter can. It also makes re-termination during a service upgrade faster since you can lift the wire straight out.
7) How many connection points does the Milbank 100A block assembly have?
Two terminals per block. If your metering configuration needs more than two termination points, you will need additional blocks or a different assembly, so count your conductors before ordering a single unit.
