How do you join an armoured cable to another to extend, a supply to a garden shed.?
armoured cable should not be outside


terminate the armour with a junction box and switch to outdoor water/weather proof cable or better still, wire in p.v.c. conduit


P.S. all outdoor wiring should be GFI protected





What actually is a GFCI?





The ground-fault circuit interrupter (GFCI) is a fast-acting circuit breaker which senses small imbalances in the circuit caused by current leakage to ground and, in a fraction of a second, shuts off the electricity. The GFCI continually matches the amount of current going to an electrical device against the amount of current returning from the device along the electrical path. Whenever the amount "going" differs from the amount "returning" by approximately 5 milliamps, the GFCI interrupts the electric power within as little as 1/40 of a second.
