The AC1988 has been designed for mounting on a 20mm or 25mm deep standard BS single gang accessory box. However, it is recommended that deeper boxes are used where extra space is required for additional cables, for example when looping in. Please ensure that there is adequate space for wiring. It is recommended that if using moulded backing boxes, please ensure that the box only has two mounting lugs as certain manufacturers do not allow adequate clearance for the Time Delay Switch terminal connections.
