Code of Practice for the Electricity (Wiring) Regulations - 2009 Edition

procedure adopted should be as recommended by the compression
joint or cable manufacturer.
(d ) Where specialist jointing kits are used, the complete kit should be
from the same manufacturer who specialises in manufacturing
products for this purpose. The method and procedure adopted
should be strictly in accordance with the manufacturer’s
recommendations.
(5) Jointing of protective conductors
(a) Protective conductors should be looped into earthing terminals of
exposed conductive parts or extraneous conductive parts. Straight
joints in protective conductors should be avoided as far as
practicable. Tee-joints in protective conductors are acceptable.
(b) Tapes should be jointed by:
(i) double riveting, or
(ii) suitable tape clamps (when clamps are used, the tape clamps
shall each be provided with at least 4 screws or bolts), or
(iii) means of exothermic or thermic welding utilizing the high
temperature reaction of powdered copper oxide and
aluminium, provided that the proper material and equipment
are used in accordance with the manufacturer’s recommended
process, or
(iv) terminal block of suitable size.
(6) Joints and terminations of non-armoured cables
(a) Non-armoured cables terminated at a moulded box or pattress, a
luminaire or other fittings should have the overall protective sheaths
carried into the moulded box or pattress, luminaire or other fittings
for a minimum distance of 13 mm.
(b) The circuit protective conductor should be terminated at the
earthing terminal provided in the moulded box or pattress housing
the wiring accessories.
(c) Where it is not required to terminate the circuit protective conductor
in an accessory, the circuit protective conductor should be coiled
away from the live terminals or any bare conductors and should be
insulated and sleeved with a green-and-yellow PVC sleeve.
(d ) Jointing of circuit protective conductors of non-armoured cable
should be in the same manner as jointing live conductors.
(7) Jointing and termination of armoured cables
(a) Cable armours should be terminated at the armouring clamps and
the inner sheath should pass through the gland.
