Leviton 1N480-41 – Frequently Asked Questions

1) Will the Leviton Series 1000 1N480 meter work on a 277/480V service?
That's exactly what the 1N480 is built for. It's configured for 1P/3W (single phase, three wire) service at 277/480V, with a 400:0.1A current ratio and a 400A maximum. If your panel is 120/208V or a three-phase four-wire service, this is the wrong unit - the wiring configuration and voltage rating are fixed on this model, not field-selectable.
2) What is the difference between the Leviton 1N480-41 and 1N480-81?
The two are the same Series 1000 dual element meter at 277/480V, 400A; the only difference is the configuration option, 41 or 81. Order by full part number, 1N480-41 or 1N480-81, so you get the configuration your job was specified for.
3) Does the Leviton 1N480 submeter come with current transformers, or do I have to buy those separately?
Meter only. The 1N480 ships as the metering unit for installation into a compatible metering socket or panelboard, so plan the rest of the assembly as separate line items on your order. Anyone quoting a full submetering package off this part number alone will come up short on the job.
4) Can I mount the Leviton Series 1000 meter outdoors or in a wet location?
Indoor only. The enclosure is NEMA 1, which is a general purpose indoor rating with no protection against rain, washdown, or dust. For an exterior wall, a parking structure, or a mechanical yard, it needs to go inside a rated outdoor enclosure or the meter belongs in an indoor electrical room instead.
5) How does the Leviton 1N480 meter report readings to a billing or building management system?
Through a pulse output. Each pulse represents a fixed increment of consumption, so it wires into a pulse input on a data logger, tenant billing system, or BMS point rather than talking a protocol like Modbus or BACnet. If your integrator is expecting a network drop and a register map, this unit will not give them one - confirm the receiving system has pulse-counting inputs before you spec it.
6) Is the 1N480 meter suitable for tenant sub-billing in a commercial building?
Yes, that's a primary use. Property managers and owners use the Series 1000 to measure individual tenant loads on 277/480V distribution so consumption can be billed back rather than absorbed in common area charges. The pulse output feeds the billing system, and the 400A maximum covers a good sized tenant service or house panel.
7) Can the Leviton 1N480 be added to an existing panelboard, or is it new construction only?
Either one. The Series 1000 is intended to integrate into new or existing panelboard setups, which is why it turns up on retrofit metering upgrades as often as on new switchboard work. What decides it is the service: it has to be 1P/3W at 277/480V, and the load has to fall within 400A.
8) What does the 400:0.1A ratio on the Leviton 1N480 mean for sizing my circuit?
It sets the measuring range. The meter senses at a 400:0.1A ratio with a 400A ceiling, so the circuit it monitors must not exceed 400A. Sizing it onto a 600A or 800A feeder puts the load past what the unit reads, and a smaller feeder is fine but you lose resolution at the bottom of the range.
