AMD 2 model forms

[Murdoch]

So I'm just doing my first AMD 2 EIC .............

.

And it made me wonder how many thousands of sparks don't have test equipment able to test the plethora of RCD's correctly now

So how many EIC's and EICR's wil be invalid!

Latest AMD only calls for AC tests now anyway. So anybody that didn't have it last month, is now all gravy again

Reg number ?

 

[Barx]

Reg number ?

without opening big book to double check wording. OSG gives ref to 643.8

My rcd tester is 25 years old and performs fine, does it apply the correct bits it should, yes all's well and good.

thanks, spot on.

just makes me wonder about one of the CPSs pushing it’s members to hand out C2’s for the “wrong” type of RCD identified during EICR’s

Oh yeah, it has to be the right type, just not tested as the right type

Clear as mud as usual ain't it?

so the BBB advocates installing equipment that the installers can’t actually test properly

it’s just utter nonsense, as usual

Here we go again

yup.

you can definitely count on me for representing the majority of hard pressed sparks.

somebody has to speak out

I still can't remember which RCD is which anyway, and have to say I'm not that bothered as long as it works as an RCD...

Say that again not hearing you.

The majority of new rcds fitted in the last 2 years will be type A. These are now the required type for most "domestic" circuits.

AC type are still OK to be installed if the circuit has nothing installed that can/will/may produce a dc feedback.

Type B and F rcds are more specialist and are used in circuits with higher dc feedback. EV chargers being an example. However some manufacturers of EV chargers fit these in the box anyway.

If your doing an Eicr and come across an AC rcd/rcbo on a circuit that can/may/will produce dc feedback then its a C3 as it complied when installed but doesn't comply with current BBB standards.

To confuse matters some manufacturers have been making rcd/rcbos to type A standards, but badging them as AC so electricians would not get confused.

Does that help clear the mud for anyone ??????????

Funny

Why should it be up to us to decide what might/might not be connected to the circuit in the future?
Sent my crystal ball in for recalibration and it never came back

As most circuits now have led lamps, varispeed drives in washing machines etc and other electronics it's a safe bet there will be dc voltage.

Fit type A as they cover the same as AC and a bit more and you won't really go wrong.

Never had my balls calibrated, sounds better than being kicked !!!

you didn't see that coming then?

Most electronics these days including LEDs have switched mode supplies fed via a full wave rectifier. There should be no DC component.

'should' and reality are often very different
