Question 1

Can i use this outside for my tumble dryer in shed ?

Accepted Answer

The masterplug ARCDKG is a cut out trip. It is upto you if you use it in your shed . But I always use it plugged into the house ring main and plug a extension lead to it then set the test button and if all is ok then I use it out side via an extension lead which gives me piece of mind. Remember if your electricity wiring has not been checked and you don't know the last time it was I would consult a electrician. But remember this product is not water proof. I hope this helps you . Kind regards anthonhurse_0

Question 2

Can I use this with an electric  chainsaw?

Accepted Answer

Yes I use it with electric lawnmower and electric jigsaw, so if you accidentally cut through your power cord it should cut the electricity so you don't get electrocuted. Just remember to press the set button, then press the test button to test its working and then press the set button again EVERY time you plug it in.

Question 3

I followed the instructions on the back,but when I plug my garden light in,it only works with orange inducator on.It gets hot on one side too.

Accepted Answer

Orange means on.. so this is good.

Getting hot on one side of it i worried about this and my pat tester said its normal and fine even with a low to medium current draw they get warm. Its not being overloaded unless you were using a few power tools at the same time such as electric saws and heaters and other high amp draw stuff. But these would trip off at these situations and also if there was any fault in any circuit or sudden high spike of voltage.

Sounds like its operating as it should

Question 4

If the main consumer unit already has an rcd fitted as most do these days will this plug trip first or will both rcds trip simultaneously?

Accepted Answer

Glad to see this asked. Although most do, stopping electric shock is not the primary function of the RCDs fitted to the consumer unit, they are to protect against failings in non-fused wiring. So say that though jumping about a wire in a badly wired plug socket, a radiator, or a light fixture say has come loose, if that wire touches anything and some current escapes (through something, back to earth, wherever) the consumer unit RCD will trip, radiators and lighting rings rarely have fuses so without the RCD nothing would prevent a fire! This kind of RCD (sub 40ms response time) is suitably quick to prevent a significant (as in potentially fatal) electric shock. Consumer unit RCDs only need a response time of 100ms, this is because they are required to handle way more current. Hope this helps! Oh by the way, in theory a plug RCD could trip first and the resulting current difference go unnoticed by the consumer unit RCD, or they could both trip, what will /NOT/ happen is the consumer unit trips but the plug RCD does not.
