Summary

ELECTRICAL INSTALLATION TECHNOLOGY I
ELECTRICAL FINAL CIRCUITS
Definition
Final circuit - a Circuit which supplies Appliances (normally via socket-outlets or other types of
connectors)
Types of final circuits
- Ring Circuit: a Circuit which is wired from a single Protective Device, being run
through an area to be supplied (via appropriate socket-outlets, connectors, etc) and
returning back to the same Protective Device, thus forming an electrically
continuous loop;
- Ring circuit can be defined as a final sub-circuit in which the current carrying and earth
continuity conductors are connected in the form of a loop, both ends of which are
connected to a single way in a distribution fuse board or its equivalent.
A spur of a ring circuit shall be a branch cable having conductors of a cross-sectional area not
smaller than that of the conductors forming the ring.
The main I.E.E Regulations relating to the ring are as follows.
1. Cable size: minimum twin 2.5mm2
and earth p.v.c or t.r.s.
2. Maximum number of socket outlets allowed: unlimited number in floor area under
100m2
, but spurs may not be more than half the socket outlets on the ring circuit,
including stationary appliances.
3. Fused 13A plugs to be used at socket outlets supplying portable appliances.
4. Fixed appliances must be protected by a local fuse, i.e. a fused spur box.
5. A 30A fuse should be used to protect the ring circuit.
6. All socket outlets in any one room must be connected to the same phase.
7. Apparatus permanently connected to the ring circuit without a fused plug or socket outlet
must be protected by a local fuse or circuit-breaker with a rating not exceeding 15A. the
apparatus must have an adjacent controlling switch
