Are you based in Frimley????????

Octopus · Nov 14, 2017

So I got a call from a customer asking me about something I did in Feb 16 - so I duely paid a visit. Knowing they had had some work done I asked if I could see the certificate..... as I didn't take mine with me!

Now bearing in mind a new fuseboard had been fitted, the kitchen had been hacked around, downlights had been fitted and a wall removed I was expecting an detailed EIC........

Er no, the EIC simply said replacement fuseboard..... which had all 10 "slots" used.

This is a photo of the test results sheet.........

You have to know the Zs to ensure the RCDs will work.
<1667 Ohms for 30mA
<500 Ohms for 100mA
<167 Ohms for 300mA
<100 Ohms for 500mA.
You cannot say it’s not applicable.
You can leave it blank because you’ve tested all the circuits protected by the RCD, or you can record the highest measured value for the circuits the RCD protects.

I’m guessing your talking about rcd testing half times 1x and 5x tests and not a zs of the rcd as they are not the same.

These values are for if you need the RCD to provide fault protection as well as additional protection. So in most situations they are not applicable.

UPDATE:

The customer contacted said spark about the concerns I had raised and he's coming back on Monday. The customer has asked if I wouldn't mind reviewing the next cert!
