Completing test sheets on circuits. With rcd protection and and rcd socket outlet

[Nige mart 50]

You have a DB with 100mA protection

You have a circuit with a 32a socket outlet with a 30mA rcd fitted - protecting the socket outlet

When completing the test sheet I’m on the understanding , the rcd protecting that circuit is 100mA and that information will be inputted on the test sheet

The socket outlet itself 30mA will be tested and recorded say on a ppm sheet or recorded on notes of the test sheet , as it is not protecting the actual circuit

A few lads at work seem confused by this and are saying you should write 30mA on the test sheet for that circuit test the socket and record them results on the test sheet

which I disagree with that

Also what if you had a circuit with multiple rcd socket outlets ?
They say test them and record highest

Same again I’m on the understanding the rcd in the DB protects that circuit
And the socket outlets should be tested separately and recorded on a Ppm sheet or something similar

I agree with you, you should record the protective device and additional protection provided for the entire final circuit.
Otherwise you create the impression that the circuit has additional protection that doesn't exist.

whatever protects the circuit is what's noted on circuit details. put in the notes box that sockets are RCD sockets

The 100ma would not be additional protection.

Sure I meant his colleagues were suggesting listing 30ma as the RCD for the circuit, creating the wrong impression.

That would be wrong as the 30mA is at the socket and not for the circuit.

I must admit if the circuit only serves one point and its one with an RCD in, I will write the results in the RCD times box for that cirucit and add a comment along the lines of "RCD times relate to RCD in ceeform socket [4P/30mA/40A/AC]" but leave the RCD details for the circuit as N/A. I think as long as its obvious to the person reading it what the situation is then its ok, even if it could be argued that its technically not correct. If you've got something like 3 RCD sockets on a radial, I'd mark the times as N/A and then squeeze something like "LHS:11.1/55.5 | Mid:11.11/55.5 | RHS:11.1/55.5" In the comments. If there was 20 of them it'd be on a second sheet while I was loseing the will to live after doing the first few of them......
