Rcd not tripping and ramp test more than 30ma

[Neil01]

A F1 for further investigation myself I was going to put a C3 and state RCD does not operate within the trip times and place no more than 12 months till next test property is in the middle of house sale thanks

I've never come across an F1 code before! I've seen people write FI for further investigation sometimes, is that what you mean? As far as this fault goes it is potentially dangerous and requires some investigation, so you code it according to the worst part of that situation which is a C2.
It is not a C3, it is quite clearly something which requires fixing, not just a recommendation for something which could be done to improve safety.
It is different to a situation where no RCD is fitted and you are recommending that one be installed to improve safety.

12months is a ridiculous retest time for a domestic installation, the recommended test interval is 10years for domestic but can be less if you feel that it is required.
The retest period is conditional on all C1 and C2 observations being rectified.

The fact that the house is being sold is irrelevant to the EICR other than maybe writing it down in the box titled reason for carrying out the EICR.

It's a Hager board RCD circuits are sockets up and down and shower. TNCS earthing tested at a socket there is nothing on as House is empty but MCBs where all on

so the rcd was not tested directly !!

Post 2 had it called first imo

Its a C2.. Unsatisfactory on report. But you should be testing an rcd on outgoing terminals with all loads disconected.

Il put it down as C2 I am going back to test at the RCD itself with loads disconnected and see what happens, iv megger the all circuits and no issues on low readings. When I tested it at socket 1 times came up 300ms so that's why I done Ramp test. I suspected it was a faulty RCD. Thanks for your help guys

Sorry, I just assumed (obviously incorrectly) that you had carried out the test properly in the first place.
Don't code anything until you have carried out the test correctly and then think about coding it.

Why would you suspect a faulty RCD from an incorrectly carried out test? You might as well IR test a socket circuit with appliances plugged in and conclude that a cable has degraded from a low reading!!

Bought an MFT off Fleabay & it didn't have any instructions with it???

me and geordie are old, bu tnot faulty. senile perhaps.

I'm sorry, have we met before?

Do I know you?

Who am I?

#21 some RCD units can be tested out at the load side with appliances plugged in & the readings are correct in fact I know of one sparks that had everything disconnected & tested his RCD's at the board & found that he had suspect readings (FAULTY RCD) bells rang out & when he tested second RCD on same board alarm bells rang.
After f... about a bit then re-tested with load on & got the results for the RCD & all ok, think this has been debated before on an early post.
maybe new to testing might have used the forum for some advice & not a bashing. (8 posts)

the recommended test interval is 10years for domestic but can be less if you feel that it is required.

In fairness that is only the recommended initial frequency. There is no recommendation for a subsequent periodic inspection as to what the reinspection interval should be.

When installing an RCD, there is always a sticker informing the consumer to test regularly by pressing the test button, I have been out of the game now for a couple of years (retired), so things may have changed, but in all my years I have not come across a customer who has done this. The switch is held in mechanically, so in my opinion I would have tested the trip a few times before doing a final check, then act accordingly.

The problem with doing that is that someone isn't going to press the Test button half a dozen times before every earth fault.

Then the label is a waste of time, but I do take your point.

Along with the mixed cable colours.

Lets all do the planet a favour and stop using them!
