Guidance for installers when making connections in consumer units

In recent years there have been an increasing number of reports of fires involving consumer units. The increase in such reports is due to a number of factors, including the effects of poor workmanship, a progressively deskilled electrical
contracting trade, increased surveillance activities by fire and rescue services and product evolution.

As a first step to improve the situation, a requirement has been included in Amendment 3 of BS 7671 published in 2015 such that consumer units and similar switchgear assemblies shall either have their enclosure manufactured from non-combustible material or be enclosed in a cabinet or enclosure constructed of noncombustible material.

At the BSI/IET working group set up to look at consumer unit fires, interested parties agreed to conduct further research into the use of the types of terminal found in consumer units and to provide guidance to assist installers to make effective and electrically sound connections.

This guidance produced by Electrical Safety First and BEAMA, provides practical advice and guidance on achieving safe and reliable connections for devices and terminal bars within consumer units and similar switchgear.

Guidance is provided on the cable preparation required to enable a safe and reliable connection to be made based on factors relating to the conductor.
