  • I need an extension lead for a freezer. Other than cost and physical flexibility, is there any issue with overspecing the lead by using 2.5mm² 3 Core?

    And as a follow-up, is there any knock on implications for the plug and socket for the lead?

    Cheers.

  • Freezers aren't high current devices, even when the compressor is running, so I'm not really sure what you're hoping to achieve by overspeccing the cable?

    The only thing I'd think about doing is swapping the inevitably 13A fuse for a 5A one (assuming the motor rating was well under 1200W), although you'd do that on the freezer rather than the extension lead. It probably also doesn't achieve very much though.

  • is there any issue with overspecing the lead by using 2.5mm² 3 Core?

    Not really but it can be a bit of a sod fitting the cable into 13A plugs and extension sockets. I'd just stick with 1.5mm cable personally as the voltage drop isn't likely to be an issue.
