What is a DC isolator switch?DC isolator switches are commonly found in solar power systems where they disconnect the solar array from the rest of the system. In this application, the DC isolator is mounted between near the solar panels or close to the solar inverter, but on the DC side. 1. Extractor fans.
How does an electrical isolator work?While it doesn't function exactly like a circuit breaker that separates the circuit automatically in case of an overload, an electrical isolator switches, it's done manually. No power-on or power-off transients (surges). When the switch is activated, it will either turn on or off, but there won't be any surges while it does so.
Do I need a BS7671 isolator switch?Also, most freezers or refrigerators have sockets that are hard to reach which means you'll have to touch or move the appliance; which could be dangerous if it develops a fault. This is why an isolator switch is required and the absence of one is a possible breach of BS7671 which recommends that all kitchen appliances be outfitted with isolato
