Blanks missing from CU in 2 senarios

[Deleted member 26818]

Which are totally open to interpretation.

Code C2 for missing blank plate.
Code C1 for exposed ‘live’ conductive parts.

 

[Risteard]

It’s not an interpretation, it’s an application of the Regulations as written.

Not sure how bins, radiators etc. would meet the BS7671 definition of exposed conductive parts... They don't form part of the electrical installation.

A metal CU does.
Metal conduit does.
Metal clad sockets do.
Face plate screws do.
Etc.

Not in the same way a buss bar does.

I would 99.9% of the time code a missing blank as C1 and I rarely give C1's.

It's a great big hole with a big piece of live copper behind it which is easily touchable!

Yes a potential danger which is not the standing of a Code 1.

What would you consider a C1?

What would you consider a C1?

I think the Code definitions are poorly defined. Code 1 Danger present, what does that actually actually represent. Code 2 Potentially dangerous is clear that there is potential for an incident. An mcb blank missing offers a potential to danger.
So what is Danger present?

Answer my question first.

 

[westward10]

No.

Not read the whole thread. I will C1 missing blanks as if a Lighting circuit trips out people could be putting there hands though that hole in the dark.

However if the bus bar is correctly shrouded where MCBs are missing it’s a C2.

As Westward said, it’s all about personal judgement

 

[ferg]

An exposed live busbar, potentially protected by nothing other than a cutout fuse.... C1 for me all day every day.

Although to be fair for the 10 seconds and pennies in parts I just deal with it there and then.

I think with that argument Westward there would never be a C1 as you could argue that a CU with it's cover left off is only 'potentially' dangerous.

 

[Spoon]

Just to add a bit more fuel to the fire. I do remember a thread where there was a discussion about the types of blanking used. Some said that they only use the din rail fixed ones. Ones that need a tool to remove.
So do the blanking plates that just push on need coding? Any small kid could take one off..

This is my point on the Code definitions. Separate Danger Present and Potentially Dangerous, they walk the same path to a hazard. What is Danger Present, something Potentially Dangerous.
