Leviton 1N277-81 – Frequently Asked Questions

1) Can I mount this Leviton single-element meter outdoors on a service entrance?
Not without additional weatherproof protection. The enclosure type is Indoor (NEMA 1), which is a general-purpose indoor rating only. Keep it inside an electrical room, panelboard area, or a separately rated outdoor enclosure if the metering point is exposed.
2) Will a 1P/2W meter work on my 120/240V single-phase panel?
The Leviton single-element meter is configured 1P/2W, single-phase two-wire, at 120V. That covers one hot and a neutral, a single 120V branch or tenant feed. A 120/240V three-wire service with two hots needs a two-element (1P/3W) meter instead, not this one.
3) How does this Leviton meter report usage to a billing or monitoring system?
Through a pulse output. Each pulse represents a fixed increment of consumption, so it wires into a pulse-counting sub-metering panel, billing system, or BAS input. There is no network or serial protocol on this unit, so if your system expects Modbus or BACnet you will need a pulse-to-protocol translator.
4) What amperage and voltage configurations does the Leviton Series 1000 single-element meter come in?
Two ordering combinations: 200A at 200V, model 1N120-21, and 800A at 800V, model 1N277-81. Pick by the service you are metering, since the amperage sets the measurement ratio range and cannot be field-changed.
5) What does the 200:0.1A ratio on this Leviton meter mean for my CT selection?
It means the meter is scaled for a current transformer that outputs 0.1A at 200A of primary current, with 200A the maximum rating. Match the CT ratio to the meter, not to the breaker size, or your readings will be off by the ratio error.
6) Is this meter suitable for tenant sub-metering in a multi-family or commercial building?
Yes, that is one of its stated uses. Single-phase tenant sub-metering and panelboard metering points are the target applications, and the pulse output feeds the billing system that totals each tenant's consumption. Just confirm each tenant feed is genuinely two-wire 120V, since that is the configuration this unit measures.
7) Is this Leviton meter made in the USA?
Yes, country of origin is the USA, which matters on federally funded and Buy American procurement work where the metering component has to be documented alongside the rest of the electrical package.
