Incoming metering
A PM750MG meter is fitted as standard in the board. The meter is fully set up for
use on a 415V 3ph 4 wire system and for use with the 1600/5 current transformers
that are installed on the busbars.
Outgoing circuit metering
Metering can be fitted to some or all of the three phase outgoing circuits in
these boards. The arrangement consists of a side extension cubicle that houses
the meters and also provides additional cabling space. Meters and current
transformers are ordered separately to meet the needs of the installation. The
necessary cable looms are included with the cubicle.
The meters are mounted on the front, hinged cover of the cubicle and can be
aligned with their associated breaker. The cubicle also contains the auxiliary
busbar that provides the 240V control supply for the meters
