FAQs (Frequently Asked Questions):

Q: What is the typical use for 4.0mm cable?
A: Commonly used for high-load appliances such as electric cookers, showers, or large immersion heaters.

Q: Can this cable be used for lighting circuits?
A: No, 4.0mm is too heavy-duty for standard lighting use 1.0mm or 1.5mm instead.

Q: Is this cable suitable for underground use?
A: Only if installed within conduit or armoured ducting designed for underground protection.

Q: Is the Earth wire insulated?
A: No, the Earth (CPC) is bare copper and must be sleeved with green/yellow sleeving during termination.

Q: Is it flexible?
A: It is a rigid cable designed for fixed wiring installations, not flexible or portable applications.
