Frequently Asked Questions
-
What backbox depth is needed for the CMA653 fused connection unit?
Requires minimum 25mm backbox depth with 60.3mm horizontal fixing centres. Standard 35mm backboxes provide adequate installation clearance for cable connections.
-
Can I connect a 3kW immersion heater to this FCU?
Yes, rated for 13A resistive loads at 250V AC, suitable for 3kW immersion heaters. Use appropriate 13A cartridge fuse for overcurrent protection.
-
What does the neon indicator show on this connection unit?
Orange neon indicator provides visual confirmation when live supply is present. Illuminates when circuit is energised, even with appliance switched off downstream.
-
Which cable sizes fit the screw terminals?
Terminals accept 3x 2.5mm² or 2x 4mm² solid conductors. 5mm diameter terminals with 2Nm torque specification ensure secure electrical connections.
-
Is this FCU suitable for bathroom installations?
IP20 rating limits use to dry indoor locations only. For bathroom zone applications, choose IP44 rated units specifically designed for moisture exposure.
