Freezer-Extension Lead Exclusion-Guarantee.

Zoomup
A customer of mine has said that the guarantee for his tall freezer is invalidated if the appliance is supplied through an extension lead.


Why is that?


How can an extension lead cause freezer damage? The appliance was running well supplied by an extension lead when I saw it.

    Whilst on the subject of plugs - which would you say had the largest contact area in terms of pin shape - round? (as in the old 15A types) or the present 13A square ones?

    I would have gone for the round option myself because arguably, the corners of the square pins do not actually make any firm contact with the female receptical.




    With round plugs, if the prongs and receptacles were both perfectly hard, the contact point would be a point. At least with square (i.e. rectangular) prongs, the contact would be a line. So square must be better.
