Electrical Connection Unit

Connection units for wiring a fixed appliance into the ring main — a boiler, a towel rail, an extractor fan. The fused version protects the appliance at 13A; the unfused 20A and 25A units are for higher-load fixed wiring.

• Check before ordering: a fused connection unit takes a 3A or 13A fuse and needs one fitted. The 20A and 25A units are not fused — protection comes from the circuit breaker.
