RCDs

Where would we be without RCDs ?

Would certainly be quieter on here!! But the Electrical Trainee would undoubtedly have other areas where they don't excel and thus we will see questions like 'why doesn't my main switch trip?'

Where would we be without RCDs ?

back to supplementary bonding i dare say...

not to mention having to actually think about how to correct a high value of loop..



beyond the realms of some that hang around here i might add....

I pressed the test button of a square D QQE RCBO to day and it exploded blowing the 63 amp main fuse customer came running in , how do you explain that to a customer , that they should press the test button every few weeks ,he looked more shocked than me , what a load of junk they are , to much reliance on RCD's and RCBO's these days , and to make it worse they have two different BS numbers one 4293 for the RCD and 60898 for the mcb side all on the same device box aint wide enough to put all those in , on the test sheet

eh?

encouraging lazy buggers to accept high levels of loop...just caus theres an RCD top end..?

or maybe its all about condition report coding in special locations?...

it could even be about forcing/insinuating unneccessary board changes on the unwary...

RCDs have their place....but their not a be all n end all...

Ive heard of one guy pushed the test button on a RCBO, for the function test, which took out a 400a MCCB
It was a old square d BS 4293 RCD/MCB.

I've seen quite a few posts about RCBOs blowing up when the test button was pressed.Does make me a bit wary of them.
