Local Isolation in Kitchens
Local isolation is generally required for all items of electrical equipment for maintenance, service & repair. Should a fault occur within an electrical appliance causing an MCB or RCBO to trip, the facility to isolate the kitchen electrical appliance from the electrical circuit would enable the MCB or RCBO to be reset.
Methods of local isolation can be achieved by the means of a suitable readily accessible double pole switch with a contact gap of at least 3mm. Depending on the maximum demand of the electrical appliance the means of local isolation could be a 13 amp switch fused spur, 13A plug and socket outlet or a 20 amp double pole isolator.
