RCD Not tripping when in contact with live conductor

[Lilyrose08]

Hi All
Please correct me if I'm wrong I was thought that an RCD should trip when you come In contact with a live conductor. Now I have had 2 electric shocks in the last 3 months and on both occasions and the RCD did not trip.The RCD was tested and passed.
Any ideas ?

Idea 1: learn safe isolation!!

The answer is obvious.

2 shocks in 3 months, you're not learning fast enough but you're also not dead.

The current passing thro' you was less than the RCD tripping current (assuming the RCD is working O.K)

Been there, done that, as have most people.

I've done it in my own house out if stupidity and tiredness.

Guys is the Op an electrician or a member of the public though, The username doesn't strike me has a sparks username.
I may be wrong it does happen!. OP can you confirm who/what you are??

Iirc this is not an electrician. Lillyrose had a problem that a lot of people were advising on hence the fairly high post count.
On the other hand it could be a spark who likes flowers

He might not be a spark and he also might not be working on his house he might just be getting a shock from a metal switch or something, if you are not a spark then please get some one out to check your electrics to make sure they are safe. If you are a spark make sure you safely isolate before you work on it.

What milliamp is the rcd it may be the wrong one.

Flowers?
What kind do you like, for after your 3rd shock!

Roses and Lillies obviously, wake up Boydy!

Complete rewire with solid gold face plates to be safe.

Two things spring to mind, firstly the RCD is rated to trip at 30 mA usually will give you a bigger shock than most people imagine. Even if a 15 mA fault current flows through you you'll know about it in no uncertain terms. Secondly if you were tinkering inside an appliance or electrical fixture and you got a shock from the live whilst you were also in contact with the neutral then the RCD won't detect this as a fault and won't trip regardless of how big a shock you get.

As previously mentioned, learn to isolate things before sticking your fingers in. You might not be so lucky the next time.

Indeed. For comparison, I can detect about 1/4 mA (250µA) by stroking the live surface with knuckles, feel 1-2mA with fingertips, and would consider 5mA a definite shock under average conditions. 30mA is a practical compromise between safety and unacceptable nuisance tripping. On 120V systems in the USA where typical leakage currents are lower, GFCI's are usually rated to trip (albeit slowly) at 6mA. I build portable electronic equipment with unavoidably high leakage currents, often 1-2mA, approaching the safe limit to run from a plug and socket outlet without a high-integrity CPC. When the tangle of extension leads gets mashed and the CPC broken, I usually get a call asking why they are getting shocks off my equipment without anything tripping...

I don't think the tripping current has been mentioned. Might even be an old ELCB
