Leviton MSTCT-1SC – Frequently Asked Questions

1) What's the difference between the solid core and split core CT versions of the Leviton Gen3 Mini Meter?
It comes down to whether you can de-energize and pull the conductor. The solid core CT (MSTCT-1SC) is a closed ring, so the feeder has to be disconnected and threaded through it, which suits new construction or a panel swap. The split core CT (MSTCT-1SP at 100A, MSTCT-2SP at 200A) opens and clamps around a conductor already in place, which is what you want for a retrofit in an occupied building where you can't drop the load for long.
2) Which Leviton Mini Meter part number do I order for a 200A single-phase service?
MSTCT-2SP is the 200A configuration, and it comes with a split core CT. The 100A configurations are MSTCT-1SC (solid core) and MSTCT-1SP (split core). There is no 200A solid core option in the line, so if you need 200A you are ordering a clamp-around CT.
3) Can I use this Leviton Mini Meter on a 208V or 240V three-phase panel?
No. The Gen3 Mini Meter covered here is a single-phase, two-wire 120V module with one CT. Two-wire means one hot and a neutral, one current measurement. A three-phase service or a 3-wire 120/240V load needs a meter built for multiple current inputs, not this one.
4) Does the Leviton Gen3 Mini Meter come with an enclosure, or do I need to mount it in a panel?
No enclosure is supplied. The LCD module and CT ship bare, so the installer provides the housing, typically mounting the module in the panelboard, load center, or a separate NEMA box with the CT on the feeder inside. Budget the enclosure and mounting into the job.
5) Can I read the Leviton Mini Meter remotely, or only at the panel?
Two ways. The integrated LCD gives a local readout of real-time and cumulative consumption right at the meter, and the unit provides a pulse output for remote data collection. Pulse output means you wire it into a data logger, BMS, or billing system that counts kWh pulses. It is not a networked meter with Modbus or BACnet, so plan the head-end around pulse counting.
6) Will one Leviton Mini Meter cover a whole apartment unit's electrical panel?
Yes, if that unit is fed by a single-phase 120V two-wire circuit at or under the CT rating: 100A with MSTCT-1SC or MSTCT-1SP, 200A with MSTCT-2SP. The CT goes on the feeder ahead of the branch breakers, so the one meter totals everything downstream. A unit fed by a 120/240V three-wire service is outside what this two-wire module measures.
7) Is 1kWh resolution accurate enough to bill tenants from a Leviton Mini Meter?
It resolves and accumulates in 1kWh increments, which is the same granularity a utility bills at, so it works for tenant sub-billing and cost allocation in multi-tenant residential and commercial buildings. If you need sub-kWh granularity for short-interval load studies, this resolution will be coarse for that purpose.
8) How many CTs ship with a Leviton Gen3 Single Phase Mini Meter?
One. Each configuration is a single LCD metering module plus one current transformer, matched to the amperage of that part number. If you are metering several tenant feeders, you order one complete meter per point, not one module with extra CTs.
9) Is the Leviton Gen3 Mini Meter made in the USA?
Yes, country of origin is the USA, which matters on public and institutional work carrying domestic-content requirements on the purchase order.
