Frequently Asked Questions
-
What backbox depth is required for the CMA2653 FCU?
Minimum 25mm backbox depth required. Standard 35mm backboxes provide adequate clearance for cable connections and meet installation best practices.
-
Can this FCU handle inductive loads like extractor fans?
Rated for 13A resistive loads. For inductive loads like motors, derate to approximately 80% capacity. Consult manufacturer specifications for specific appliances.
-
What appliances typically use unswitched FCUs?
Boilers, immersion heaters, extractor fans, and fixed appliances requiring permanent connection. LED indicator shows circuit status without switching control.
-
What torque setting for terminal connections?
Tighten screw terminals to 2Nm using Ø5mm flat-blade screwdriver. Over-tightening may damage brass terminals or conductor strands.
-
Does this meet Part P Building Regulations?
Yes, BS 1363-4 and UKCA compliant for domestic installations. Installation by competent person or notification to Building Control required.
