Masterplug Single Socket RCD Safety Adaptor, Black

Sturdy, easy to use and does its job. Will use for gardening equipment for added protection.

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!

It does the job

Fast delivery, well made, works out of the box.

Sturdy adaptor, just the job

This is a no brainer for people using mains powered electric tools and gardening equipment. It is a reasonably priced effective RCD safety plug. I cannot comment on it’s longevity or robustness at this stage

Simple to operate, second one of these I've used. Great for peace of mind.

Does the job. Easy to use.

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

Didn't work at all. The casing does appear to be strong, but certainly looked low quality in finish and construction. However the important bit is where it failed, which is that it couldn't power anything when plugged in. The orange indicator never appeared.

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.
