What our customers say

Dear Sir

I would like to highly commend and recommend you for my recent order. We have many suppliers for different products but, unlike most, you packed yours superbly. I have tested each bulb and each one works. You also delivered it before the allotted time frame.

So, thank you very very much for your excellent service.

Kind regards

Shirley Boarer

RCD Facts

There are two types of RCD’s: Active & Passive, also termed Latching & Non-latching.
Both types are accepted by British Standards and it is up to the user to choose the type of RCD that is most suitable for their application.

Active (Non-latching) - RCD’s switch off if power to them is turned off. Every time the appliance is turned off, the RCD will trip & have to be reset by going to the socket.

Passive (latching) - RCD’s “remember” what state they were in prior to the power being switched off.
On the resumption of the power, the power will then continue to be supplied to the appliance, & the RCD does not need to be reset.
