Answer: In some cases
Explanation: The provision of isolating devices for extract fans in bathrooms or shower rooms is not specifically addressed in BS 7671. A fan isolator mounted adjacent to the fan would fulfill the requirement for switching off for mechanical maintenance. Regulation 537.3.2.2 requires the open position of the contacts of such a switch to be clearly indicated. Taking all of the above into consideration the following is therefore recommended: Extract fans having a ‘run-on’ timer: A BS EN 60947-3 fan isolator mounted adjacent to the fan would provide the appropriate means of switching off for mechanical maintenance. Where the isolator switches both the switch wire and permanent line conductor, this would also provide a means of local isolation where access to live parts is required. The isolator should be located adjacent to the fan outwith Zones 0, 1 and 2 in accordance with Section 701 of BS 7671:2008 (2015). The switch need not necessarily interrupt the neutral conductor.
