Electrical Distribution Inspection & Testing

Electrical distribution systems require inspection & testing both upon installation and throughout their operating lifetime as recommended by the I.E.E. Wiring Regulations (BS7671).

Inspection & testing verifies that appropriate standards have been met, that the necessary level of protection is present and that the system is running within its design criteria.

Testing should follow the recommended procedures laid out in the wiring regulations and in official guidance notes for any special locations present.

A full visual inspection should be carried out to ensure correct selection & erection of components & compliance with British Standards, suitability for the environment, correct connection & identification, adequacy of mechanical protection, protection against direct & indirect contact and tracing & identification of all circuits within the installation

Electrical tests are then carried out such as - Continuity of protective conductors & equipotential bonding, continuity of ring circuits, insulation resistance, Polarity, Operation of switching & isolation devices & RCDs, earth fault loop impedance & prospective fault current and Earth electrode resistance.  Following testing a full documentation set is compiled giving full circuit details and test results along with details of fault found with photographs and recommendations for rectification.  All documentation can be issued in printed format and emailed in PDF format for printing from any computer.

We can also provide schematic diagrams and location maps for equipment in a variety of formats including DXF.
