Compliance with certain aspects of the Building Regulations Part L2 has required the engineering and installation of meters to gather energy usage data. Merlin Gerin, a brand of Schneider Electric, has announced a simple and elegant solution to the problem by offering its Isobar 4c 3 phase split metering lighting and power B type distribution boards with inbuilt meters and communications options.
The Building Regulations Part L2 a and b demand sufficient facilities to account for 90% of each fuel type by end use category. Since 2006 it has also been required to have automatic meter reading and data collection facilities for all new buildings over 1000m2.
The new Isobar 4c gives metering of total load plus separate metering of section 2. All control wiring current transformers and protection for meters are included and fitted, with outputs wired to terminals. For remote data collection and communications, an Ethernet gateway and DC power supply can be supplied for retro-fit. The Power quality meters themselves are the state of the art PM750MG models with both pulsed output and Modbus communications.
Isobar 4c distribution boards can also be supplied with extension enclosures for fitting of Surge protection and remote switching if required for fitting on site to extend the functions of the distribution boards.
For split metering units the Isobar 4c 125 or 250amp boards come with a unique new split busbar (for which a patent is applied for) for lighting and power – in three combinations of 12/8, 14/6, 16/4 - but a single overall isolation device. Standard incomers can be used together with split earth bars for ease of wiring.
Like all Isobar 4c boards, there is an individual unique outgoing MCB connection slider; units are designed manufactured and tested to BS EN 60439 1 & 3; ingress protection is to IP3X to BS EN 60529; voltage rating is 400/415V; and the cable capacity of neutral and earth bars is 25mm2.
