Question

Four single-phase circuits. Each circuit is rated 50A and 230 Volts. The length of
the circuits is 32m. The circuits are protected by 50A BS 88-2 fuses. These
circuits are supplied by two-core cables of 25 mm² using Reference Method B.
Part of the circuits will be through an area where the ambient temperatura is
35◦C. The earth loop impedance external to the installation Ze = 0.3 Ω. The
operating temperature is 70◦C and the c.p.c. conductor cross-sectional area is 10
mm².
Determine:
a) The ambient temperature factor (Ca) and the grouping factor (Cg) and the
tabulated current It.
b) The voltage drop if the power factor of the load is 0.8 lagging.
c) Check the validity of the circuits for shock-risk.
d) Check the validity of the circuits for the let-through energy.
e) The maximum length permissible for each circuit.
