IR testing and RCD's

[apprentice87]

Hi All,

Now here is an interesting thing i just found!!!!!!

This is from the "BEAMA Guide to the Selection and

Application of Residual Current Devices"

7.2.3 Insulation tests

When insulation tests are carried out on an installation, the applied voltage should not

exceed 500V d.c. (RCDs are designed to withstand this voltage).

An RCD in circuit may affect insulation resistance test results. It may be necessary to

disconnect RCDs for the purpose of these tests.

The companies involved in the writing of this guide were apparently;

Eaton Electric Ltd

Electrium Sales Ltd

Hager Engineering Ltd

Legrand Electric Ltd

MK Electric

Moeller Electric Ltd

Schneider Electric Ltd

Siemens plc

Timeguard Ltd

Western Automation R&D Ltd

So, no worries there then!!! If you do zap one, [As i did accidently the other day!!!] just test it afterwards to make sure and carry on as normal!!

Just google "beama rcd" and click on the link. LOADS of interesting stuff in there!!!
