ABSTRACT
It is vital for a satisfactory outcome to any electrical installation that it is designed correctly. It does not matter whether the installation is a single circuit or a full installation, the same rules apply. The statutory document that applies to all electrical installations is the Electricity at Work Regulations 1989 (EWAR 1989). These regulations are made under the Health and Safety at Work Act 1974 (HASWA 1974) and quite clearly state that although BS 761 wiring regulations are non-statutory, compliance with them will be likely to achieve compliance with the relevant parts of the EAWR. Once it has been decided that the supply is suitable for the requirements of the installation the next step is to decide on the types of circuits required. This will need to include anything within the proposed installation that will require an electrical supply. All parts of all installations must be selected and erected to prevent damage by impact, abrasion, penetration, tension or compression.
