Target time 5 hours 30 minutes

This is the wiring of an installation, which includes a range of electrical circuits, each devised to assess a candidate's proficiency in particular aspects of electrical work. The electricity supply will be provided from a TN-S three phase 4 wire 400V system.

The illustration (Figure A) shows the layout of components on the unit.

INSTALLATION ASPECTS	SKILL ACTIVITY
Main and Supplementary Equipotential Bonding	Measuring, clipping and dressing, terminating and fixing bonding clamps on service pipes etc.
Circuit Wiring Lighting Circuit	Install PVC insulated cables for the two-way and intermediate lighting circuit. Install key operated override 'on' switch adjacent to the intermediate switch.
Industrial Socket Outlet (400V)	Install and connect the 16A triple pole and earth socket outlet to the output terminals of the 20A TP&N switchfuse.
Three Phase Motor Circuit	Installing cables in trunking and conduit; terminating and making connections between a three phase squirrel cage motor, a motor starter, a remote start/stop/inch station warning indicator lights, with the aid of a wiring diagram (Figure C)
Circuit Wiring - Ring Circuit	Installing cables in metal and PVC trunking and PVC conduit; terminating and making connections from the distribution board to:- a ring circuit of 13A switch socket outlets.- a one gang 13A socket outlet to supply a tubular heater via flexible cord and 13A plug.

Composite Installation - Functional Operation

After the installation has been inspected and tested each candidate will be required to demonstrate that the following final circuits operate correctly:

Two way and intermediate switched lighting circuit
Operate the Landlords Key Switch
Operate the Emergency Luminaire Key Switch to effect simulated mains failure
Ring circuit socket feeding heater
Motor and control circuit
