Absolute bargain of a price for a potentially life saving piece of electrical equipment.

If you don't know what it is, then read this ;

A residual-current device (RCD), or residual-current circuit breaker (RCCB) is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance may indicate current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. RCDs are designed to disconnect quickly enough to prevent injury caused by such shocks. They are not intended to provide protection against overcurrent (overload) or all short-circuit conditions.

I always use one when using power tools in homes other than my home

comes up as £5 delivery no collect at store for me

£8 inc delivery for me as well.

Would need to spend £50+ to get free delivery on this

Had one of these for 18 months now, but it it took until the third before I got one that worked. Does the job spot on.

Keep your receipt and try it out straight away.

...and this is hot because??????????

It saves your life!!!!!

I have always used one, last week for the first time distracted whilst cutting the grass ran over the cable and power shut off instantly. Big flash but in a millisecond the power is cut - no brainer

changed my fuse board with a british general one off screwfix for £60
covers the full house ..........

Wouldn't the trip switches in your consumer box trip if you cut the wire?

I have no knowledge on the subject - genuine question.

Thanks.

I've never had one of these and haven't died yet.

Its more a tool for tradesmen. Seen them use this a lot when using multiple tools in unknown locations.

Great price.

Not so....

If you go to your local store you can ask for the item to be delivered to the store at no extra cost, it will be within 24 hours.
I did this last week when I bought a few items which were not available as "click and collect". They phone you when the item is in sore.

I have an RCD fuse box. Do I need one of these as well?

Would like to know the same as I didn't bother buying one when we moved in for the above reason.

Been this price on amazon for ages.

Note its a add on item.

I just cut the main electricity cable that comes into the house to be on the safe side.

17th edition will see the end of these

No, if you have a RCD covering your whole house, using one of these isn't really necessary. Older RCD boards may have single RCD which covers the whole house (but can cause nuisance trips) but Modern boards now tend to have 2 RCDs (split load) but may have a circuit that isn't covered by RCD (ie one that serves the fridge/freezer) so if you plug your lawnmower into the non RCD circuit you won't be protected.

Also note that if you have an older style fuseboard with trip switches (I have an old wylex board where the trips have essentially just replaced the fuse wire plates), these ARE NOT the same as RCD protection, they are effectively just a fuse, and whilst offering some extra protection over a fuse wire, will not likely cut the power off quickly enough to avoid serious injury.

I always use these circuit breakers for any power tools or outside power if possible.

Only on new builds or upgraded electrical installations, there's plenty of houses out there with very old wiring still (like my old house and my current one!)

I use one of these. I've cut through the power cable twice with my hedge trimmers and neither time did it trip out

My mum in law has one of these connected to every bit of electrical equipment that can be used outside, despite living in a new build and having a split RCD.

Suppose it depends how far you are from a store, but not a bad suggestion if it works out for you

Seems like an expensive way to test if it works. Perhaps just use the Test button.

It does cut out with the test button. My more scientific method gives a more accurate result. oO
