If There Is A Fault Or A Short In The Tool You Are Using, The Unit Cuts The Power Very Quickly, Reducing The Risk Of Electr Review: good quality - It works well and is made of good materials, but if the power goes out you will have to restart it manually. Review: An invaluable product....... - 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 desertcart 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! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000RZDNZM | | Best Sellers Rank | #633,379 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1,610 in Hardware Plugs #2,747 in Biscuits & Plugs | | Brand | Masterplug | | Brand Name | Masterplug | | Circuit Breaker Type | Standard | | Current Rating | 20 Amps | | Customer Reviews | 4.5 out of 5 stars 5,526 Reviews | | Global Trade Identification Number | 05015056379500 | | Item Weight | 100 Grams | | Manufacturer | Masterplug | | Model | ARCDKG-ZD | | Mounting Type | Surface Mount | | Number Of Poles | 1 | | Number of Poles | 1 | | Part Number | ARCDKG-ZD | | UPC | 798256128950 | | Voltage | 240 Volts | ## Product Details - **Brand:** Masterplug - **Circuit Breaker Type:** Standard - **Current Rating:** 20 Amps - **Mounting Type:** Surface Mount - **Number Of Poles:** 1 ## Images ![Safety RCD Adaptor - Image 1](https://m.media-amazon.com/images/I/81VN9QYw9eL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good quality *by E***S on April 20, 2026* It works well and is made of good materials, but if the power goes out you will have to restart it manually. ### ⭐⭐⭐⭐⭐ An invaluable product....... *by I***Y on September 7, 2012* I have been using one of these RCD Adaptors for several years now, always with electric tools (both inside and outside).
