When code a defect which of the following is an example of a C1 classification code?

The second number of an IP code relates to which type of protection?

Where the use of an RCD is provided for fault protection only, what would be the maximum setting of the residual current?

Under what circumstances would remove the need for a ring-final continuity test during periodic testing?

Questions 17 – 21 relate to the following scenario

There is a continuity test to be conducted on the main protective bonding conductor within a large industrial installation. The gas installation pipe work, water pipe work and steel framework of the building have all separately run conductors connected to the MET. Each conductor is concealed at various parts along their run. All connection to the extraneous conductive parts are remote from the MET.

Before the conductor can be disconnected from the MET, what needs to take place?

If the conductor to the gas pipe was 10mm2 and the length of the cable was approximately 27m. What would be the expected reading when tested on the pipe work after the clamp?

Which of the following instruments would be used to carry out this test?

What additional items would be required for this test and the considerations needed for this item?

When testing an RCD to BS EN 61008 at 1 x I∆N what would be the maximum permitted disconnection time?

When carrying out an external earth fault loop impedance test what must be disconnected?

The maximum permitted value of voltage drop for a 230V power circuit would be which one of the following values?

What would be checked by visual inspection to verify that Additional Protection is suitably provided by an RCD?

If the Main Protective Bonding Conductor cannot be seen throughout its length what should be undertaken?

When is it acceptable to enter a cross against any item detailed within the schedule of inspection for new works?

How would a non-compliance be recorded on an inspection schedule during a periodic inspection?

What would generally be the most common reason for crackling/arching sound coming from an existing lighting switch?

What would be verified using the sense of touch during an initial verification?

What code would be given where access to a room is limited and the inspector suspects corrosion to a bonding clamp?

What classification code would be used when discovering a severely damaged switch fused connection unit?

What IP rating is suitable for jets of water from any direction?
