Milbank SC6128-XL – Frequently Asked Questions

1) Is the Milbank SC6128-XL a self-contained meter socket or is it for CT metering?
The SC6128-XL is a transformer-rated socket, not self-contained. It belongs to Milbank's CT20 family, carries a 20 continuous ampere rating, and takes 12-10 AWG on both the line and load side. Those wire ranges are instrument-transformer secondary conductors, not service conductors, so the actual load current is carried by the CTs and the socket only sees the metering circuit. If you need to run the service through the socket itself, this is the wrong part.
2) Will a 13 terminal ringless socket work for 3 phase 4 wire 277/480V metering?
Rated 600 volts AC at 60 hertz, 3 phase, with a 13 terminal jaw configuration and a single meter position, so it covers 277/480V service metering within that 600V ceiling. The 13 jaw arrangement is what lets it carry the test switch and VT pack provisions alongside the meter. Your utility has to approve the socket for their meter form before you set it.
3) Can this Milbank meter socket be installed outdoors?
Yes. The enclosure is Type 3R, which is the standard rain-tight outdoor rating for meter equipment, and the body is G90 galvanized steel with a powder coat finish for corrosion resistance. Note the socket is listed as Non UL Listed, so if your AHJ or utility requires a UL listed socket on the project, confirm that before you buy.
4) Does the SC6128-XL include a main breaker or a meter bypass?
No to both. It is a straight metering enclosure: zero main breakers, no main breaker provision, and no bypass provision. Overcurrent protection has to come from separate gear ahead of or behind the socket, and if your utility requires a lever bypass for hot meter changes, you need a different socket. There are also no receptacles in the enclosure.
5) What are the dimensions of the Milbank SC6128-XL and how does it mount?
Enclosure measures 4.844L x 20W x 22H inches and it is a surface mount unit, so you are fastening it flat to a wall or a strut rack rather than recessing it. Allow the full 22 inch height plus working clearance in front. The shallow 4.844 inch depth keeps it tight to the wall, which matters when it is going on a busy exterior riser wall alongside the CT cabinet.
6) Can I bring conduit into this socket from underground, or does it have to be overhead?
Either one. Cable entry is rated for overhead or underground, and the unit ships with a small closing plate covering the hub opening. For an overhead service you knock out and fit a hub of the right trade size; for an underground feed you leave the closing plate in place up top and enter through the bottom. The hub itself is a separate item.
7) How do the CT secondary and VT leads land in this socket, and how do I ground it?
Terminations are single mechanical lugs sized for 12 to 10 AWG on both line and load side, which suits CT secondary and potential leads. Grounding is by a ground lug in the enclosure. Insulation is glass polyester, which holds up to the heat and dielectric demands of a 600V metering base. There is also a test switch provision and a VT pack provision, so the switch and VT pack are specified separately from the socket.
8) Is a ringless meter socket the right choice, or do I need a ring-type?
Ringless sockets like the SC6128-XL use a sealable cover over the meter rather than a separate locking ring, and many utilities specify one style exclusively in their service requirements. Check your utility's meter socket standard first: if their book calls for ring-type, this one gets rejected at inspection regardless of the electrical ratings. Also worth flagging on a spec job that this unit is Non UL Listed.
9) I need to meter several tenants in one building. Can I use the SC6128-XL for that?
Not as a multi-tenant unit. This socket has a single meter position, so it meters one service point. For a building where each tenant needs its own utility meter, you would use a multi-position meter stack or one socket per tenant. Where the SC6128-XL fits is a single large 3 phase service, typically the house or main service, being metered through current transformers.
10) What is the exact part number to order this Milbank socket?
Milbank SC6128-XL. It is the 13 terminal ringless CT-rated socket with small closing plate, test switch provision and VT pack provision, rated 600V AC, 20 amp continuous, 3 phase. When you submit it for utility approval, the SC6128-XL number plus the CT20 family designation is what the meter department will want to see.
