ARCDKG Safety RCD Adaptor

It works well and is made of good materials, but if the power goes out you will have to restart it manually.

I have been using one of these RCD Adaptors for several years now, always with electric tools (both inside and outside). About a year ago I decided to install a chest freezer in my shed; having discovered the prohibitive costs involved to run a new circuit outside I decided to run electrical cable to the shed inside protective conduit. The power would then need to come from one of the sockets in the kitchen, and although I would be very carful with the construction there was always the chance of water getting into the wiring due to the nature of what I have built. So this is what I did, and I purchased another one of these Masterplug RCD Adaptors to run the current through, just in case a 'leak' occured and the circuit blew; I could not risk this resetting the main RCD for the kitchen, this would have caused no end of problems! It has now been up and running for approximately a year and it has worked perfectly (touch wood!). It has to be reliable because we have our freezer at the other end, and this contains most of our food, if it were to go wrong it would obviously cause us big problems. It is an extremely simple device to use; as long as the little light is on then the current is working properly. There is a reset button to use if the circuit is broken, and a test button to show that the device is working as it should. It is well proportioned and is barely wider than a standard plug, so it is possible to use the other socket if this device is used on a two gang plug socket; it is worth bearing in mind though that when a plug is inserted the whole set-up does extend quite a distance from the wall, it is not an excessive amount but is worth taking into account if you plan to use the device in a restricted space. Overall a really great product, and to be honest I can't understand why anyone who uses any sort of power tools (particularly outside) wouldn't have one; the RRP on Amazon is currently £13.25, but it is being sold at the reduced price of just £5.74, this is outstanding value and is about half the price it is being sold for at B&Q. Highly recommended!

If you are in the garden you need one of these

I wanted to use this to prevent the mains from tripping, however the mains still ends up tripping, which is sad. I'm not sure if there's a way to prevent that - defeats the purpose of this plug to some degree but potentially useful otherwise when used with a power tool.

I have trusted Masterplug RCDs for twenty years and have never had any problem with them. The design doesn't appear to have changed much in that time either. I lost one and bought this to replace it. Everyone should have one and they are very reasonably priced, highly recommended and not a number 1 best seller in RCDs (at time of writing) for nothing. You may buy one for the obvious hazard of using a lawn mower, hedge trimmer, circular saw or other power tool where there is a chance that you might cut or damage the cable. You might get for your Christmas lights, fish tank pump, leaky washing machine, pressure washer or dehumidifier that keeps getting walked into, or a leaky kettle, where there is a risk or worry that water may mix with electricity. But also if you have one in stock and something unexpected happens you will be glad you had it for safety and peace of mind. For example, an appliance you rely on becomes suspicious like a phone charger getting hotter than usual, or you buy and appliance second hand and don't trust it, or you are suspicious of a cable that may have been damaged but looks ok, or you're going to hoover the car but it looks like it might rain. So many times I have been glad to have one handy. It will cut out when there is a very small current leak and before your mains trip switch or fuse goes and is designed to save your life by cutting power very very quickly. It is money well spent, cheap peace of mind and this particular product is the only one I would buy because I feel I can trust it. Highly recommended.
