Installing a meter box is a simple job that should be done correctly the first time to save delay and costly rework later. The requirements for siting, size and who can do the work are covered in this page.
Siting and Height Rules
An outdoor electric meter box needs to be installed between 375mm and 1,500mm above finished ground levels. This is measured to the centre of the meter reading position. In addition, the outdoor electric meter box must be at least 300mm away from any gas meter and associated pipework.
Depth and Internal Dimensions
The internal depth of the meter box plus the meter, cut-out fuse and cables must be deep enough to allow for all the necessary components to be installed within the box without being forced. Typically this would be in excess of 210mm and require a large enough internal volume to house all the components listed above. The DNO’s technical standards should be checked in relation to the required cabinet size prior to order.
Weatherproofing Rating
The enclosure must be weatherproof enough to prevent rainfall getting in. This means at least IP44 (water splashing against enclosure from any direction; protection against solid objects with maximum size of 1mm). However, for particularly exposed situations, consideration should be given to taking the rating up to IP54. Electric Meter box is covered in more detail at www.meterbox.co.uk/electric-meter-boxes.
Door Swing and Access
The door to the meter box must open 180 degrees, and be able to be opened by the meter reader and DNO engineer. Also, nothing must be fixed against the cabinet (such as pipes, walls, etc) which could stop the door opening.
Who Can Do the Work
The civil work for installing an electric meter box can be completed by a builder or electrician, but connection to the electricity supply is a totally different issue. Connection to the live network must be completed by the DNO or an approved contractor.
Getting the details right the first time will save time and money and avoid an expensive return visit.
