Niceic cert filling in on software programme

[cliffed]

Wondering why they isn’t a Zs box to fill in,& if Connected to origin do not fill in box.
Also altered the Rcd times,now just entering the x5 trip time.
Why is there no N-E insulation reading ,& a L-L entry,which I would take to be L-N.
Just pondering these thoughts,will phone helpline next time in office,but any ideas.

An RCD is a residual current device (RCD).
An RCBO is a residual current device (RCD).

both are RCDs

 

[Mike Johnson]

So why do we recommend an all RCBO board and not a all RCD board?

Not sure what you mean.

 

[Mike Johnson]

No I am sure you don't.

 

[Ian1981]

Rcd is a generic term for a family of devices, rccb, rcbo etc.

 

[Mike Johnson]

Except that in general terms when referring to an RCD most mean a unit without overload protection, but when referring to an RCBO most mean a different type of unit.

Im agreeing to disagree on this one.

What sort of meltdowns over terminology are we going to experience when AFDD RCBO boards become the norm?

 

[Mike Johnson]

Will AFDD's ever become the norm, or will the manufacturers take the bull by the horns and combine them?

That’s my point. Most that I’ve seen are combined devices, so do we need a new form for a board filled with AFDDRCBO’s as well as a different one for split load boards, and another one for all RCBO boards?

Or can we agree that the current forms have space to record the required information for each part of the device as required and keep on using them?

 

[Ian1981]

For when it askes for the BSEN number and if you have a combination of an AFDD and RCBO then write them both in the box
62606/61009

Live/Earth includes the neutral to Earth insulation resistance, as well as the line (phase) to Earth. Live/Live is not only phase to neutral, but also between all phases, and these to the neutral.

It's probably the Aspergers kicking in, everything must be correct and in order, to me an RCD does not do the same job as an RCBO therefore should not be listed in the same way.

RCD is a generic term. What you are describing as an "RCD" is, in fact, an RCCB (residual current circuit breaker). This is merely one type of RCD.

 

[Mike Johnson]

Of course there is, but as we deal in specifics on everything else why don't we when describing the units we put into a DB?

This is my point I don’t do an all rcbo board I do a split load rcd but I see the pros and cons of both, on the test form if it’s rcbos you will enter each rcbo reading individually normally round about the same, and then rcd covering few circuits is the same for each circuit
