Finger barriers, tip size not exceeding 4mm (recommend 2mm or less), propes fused with high
breaking capacity fuse with rating not exceeding 500mA - Answers What do GS38 propes need to
have?
Adequately insulated, colour coded (ie DC voltage), flexible, sheathed, a correct length and no
exposed conductors. - Answers What do GS38 leads need to have?
Checking IP ratings, no broken fittings, signs of burning, ect. - Answers How would you use sight
during inspection?
Connection of conductors, checking barriers and enclosures, detecting overheating of equipment, ect.
- Answers How would you use touch during inspection?
Arcing caused by load, equipment noise (ie motor bearing problem that causes a load grinding sound),
ect. - Answers How would you use hearing during inspection?
Equipment is overheating, burning of adjacent building materials, loose connections under load, ect. -
Answers How would you use smell during inspection?
Visible damage, leads aren't damaged, instrument is calibrated. - Answers All test equipment MUST
be checked before use for?
It is carried out to ensure a new installation or new circuit has been designed, installed, inspected and
tested in accordance with bs7671. This confirms the installation is safe and suitable condition for use.
- Answers Why is initial verification carried out?
It is carried out to assess the on going safety of the existing electrical installation. This is NOT a
certificate, as a certificate must have all inspection and testing criteria. - Answers Why is periodic
inspecting and testing carried out?
The designer, the installer and the inspector all need to sign the certificate to state the installation is
safe and suitable. - Answers Who needs to sign the initial verification certificate? and why?
Shock, burns, arcing, explosion, poor knowledge of the system you are working on, inadequate
information to enable safe or effective inspection and testing (ie no diagrams) - Answers Risks to

Electrical installation certificate (EIC) which must include:
- Schedule of circuit details
- Generic schedule of test results
Minor electrical installation works certificate. - Answers What forms are completed and given for
initial verification?
Electrical installation condition report, condition report inspection schedules and generic schedules of
test results and circuit details ( which are the same for EIC) - Answers What documentation has to be
completed for periodic inspection and testing.
The extent and limitations of the report. The reasons must be validated. - Answers What must be
agreed with the person ordering the work for periodic inspection and testing.
It is used where an alteration or addition is made to an existing circuit, such as adding a light to an
already working light circuit. If it involves alterations and additions to many circuits a EIC could be
used instead. - Answers What is a MEIWC?
IP codes indicate the degree of protection of ingress protection.
X stands for 0, which means not protected. - Answers What is IP codes? What does X stand for?
- SELV and PELV
- confirmation of insulation of live parts. (Should be carried out to ensure no damage has occurred
during installation)
- Barriers and enclosures need to be checked to ensure a protection level of at least IPXXB or IP2X.
