Frequently Asked Questions
-
What backbox depth is required for the CMA020 fan isolator?
Minimum 16mm depth backbox required, compatible with standard 25-47mm depth enclosures for flush mounting installations.
-
Can this isolator switch handle 10A fan motor loads?
Yes, rated for 10A resistive loads at 250V. Suitable for standard bathroom extractor fans and ventilation equipment.
-
Is the CMA020 suitable for bathroom zone 2 installation?
IP20 rating limits use to areas outside bathroom zones. Install minimum 0.6m from bath/shower edges per BS 7671.
-
What cable sizes fit the screw terminals?
Terminals accommodate 4 x 1.5mm² conductors or 2 x 2.5mm² cables. Tighten to 0.5Nm torque specification using 3.5mm screwdriver.
-
Does this fan isolator meet Part P building regulations?
BS EN 60669 compliance ensures regulatory approval. Installation in bathrooms requires qualified electrician for Part P notification.
-
Why does the switch not work after installation?
Check L1, L2, L3 terminal connections are secure to 0.5Nm torque. Verify correct live feed to appropriate terminal per wiring diagram.
