Eaton’s metering solutions save time and money because they avoid the need to order factory-built assemblies with bespoke metering. There is no need for contracts to be delayed while installers wait for boards to be built; instead they can order distribution boards and meter packs through their normal distributor when they are needed.
The meters are pre-installed in the enclosures, together with current transformers and wiring looms, so that installers have a minimum of on-site wiring. Installations can be completed on time, at a competitive price, and with improved margins.
Eaton’s L2 metering products fall into two broad categories:-
1. Distribution boards with integral meters.
2. Separate meter packs for use with Memshield 3 panelboards and distribution boards.
The range includes solutions for Type A (single-phase) and Type B (three-phase) duty.
The options include split metering so that lighting and small power loads can be metered separately at sub-distribution level.
Some meters are for direct connection (i.e. the incoming supply feeds into the meter which then feeds the distribution board) but the majority use current transformers. All provide for visual readout and pulsed output kWh measurement and many can provide visual indication of other parameters such as voltage, current, power factor etc. OFGEM and MID certification is normal.
Eaton’s split metering solution can also save sub-mains cabling – where meters would normally be installed in a main switchboard with separate cables to feed lighting and small power loads, it is now possible to use a single feeder to the distribution board and carry out the metering at this point

Double meterpack for two Type B distribution boards
160A and 250A Meterpacks for installation directly beneath two Memshield 3 Type B distribution boards (typically for separate supply of lighting and small power). Pack includes a rotary incoming switch disconnector, two multi-function meters, two sets of CTs and meter voltage reference fuses all pre-wired for easy installation. Connection tails also supplied.
Incoming and outgoing metering options
Both incoming and outgoing metering options are available for Memshield 3 panelboards to ensure Part L2 Building Regulations Compliance.
Eaton has made it easy to incorporate metering with a plug-in cabling system that provides faster and error proof installation.
The risk of errors is eliminated and a meter can be easily wired in less than 15 minutes.
