Milbank TB100-47 – Frequently Asked Questions

1) What amperage does the Milbank TB-47 test block come in?
Two ratings are offered: 100 amp (TB100-47) and 200 amp (TB200-47). Both carry the same 600 volt AC rating and the same 2-terminal, surface mount body, so the amp rating is the one thing you pick between. Match it to the service the meter socket is serving, not to the meter itself.
2) Will a Milbank test block fit in my existing enclosure or meter pedestal?
The body measures 9 x 5 x 4.5 inches (length, width, height) and mounts on a surface, so you need a flat backpan or panel area with that footprint plus wiring room in front of the lugs. In tight can-mounted retrofits that 4.5 inch depth is usually the number that decides it, so check the clear depth from the backpan to the cover before ordering.
3) What does a test block with line and load bypass actually do on a metering installation?
It gives you a place to isolate the meter without dropping the customer. The line and load bypass assembly carries the load around the metering circuit so the meter can be pulled, tested, or swapped while the service stays energized downstream. That is the difference between a test block and a plain terminal block, and it is why utilities and commissioning crews specify one.
4) Can I use this Milbank test block on a 480 volt three phase system?
It is rated 600 volts AC, so 480Y/277 and 480 delta are inside the rating on a voltage basis. The limit is the terminal count: this is a 2-terminal block, so it lands one metered pair. A three phase installation needs more poles than this block provides, so size the terminal count to the number of conductors you are metering.
5) What kind of wire terminations does the Milbank test block use?
Mechanical lugs, so conductors land directly under a set screw with no crimping and no special tool beyond a torque driver. That suits field terminations in copper or aluminum where you want to be able to back the conductor out later during service work. Bring the lugs up to the torque marked on the block.
6) Is the Milbank TB100-47 a replacement part for an existing socket, or a standalone device?
It is a replacement metering accessory, not a complete enclosure. The block is the internal assembly that mounts to a surface inside the equipment; you supply the enclosure, the mounting hardware, and the conductors. If what you actually need is a whole meter socket or a ringless can, this is not that part.
7) Can a test block like this be used for periodic meter accuracy testing without an outage?
That is what the bypass is for. With the line and load bypass assembly made up, the metering path can be opened for test leads or a test meter while the service conductors stay carrying load through the bypass. For a facility on a demand rate where a planned outage is expensive, that is the whole reason to have a test block in the run.
