Live cable taken straight off busbar..Reg no. required.

[dtec dave]

Evening...Can anyone tell me which reg this breaks??

It feeds a switched fuse.

What do you think is wrong with it?

 

[Andy78]

Depends how far away the switch fuse is. Which reg do you think it breaks ?

 

[Deleted member 9648]

Where is it going and how long is it?
Have a look at the regulations on omission of protection for overload and position of devices for protection against fault current.

 

[dtec dave]

The next part of my question should have been 'if any regs at all'.

It just doesn't seem right, those nuts/bolts are to fix the busbars in place, not for additional cables to fix to.

 

[dtec dave]

It's not the fact that it is feeding a switched fuse, that is right next to the db, it's the fact that a cable has been crimped on to a busbar that bothers me, so asked for clarification.

 

[Deleted member 9648]

There are regs, have a look at the regulation I mentioned in post #4 and see what you think.

 

[Deleted member 9648]

I cant think of any regulation that prevents lugging a cable to a pre-drilled bolt on a busbar.

 

[dtec dave]

Ok..that's the answer I was looking for then!!! Cheers

How about the cover missing off the busbars? Note the screw holes.

Is it over 3 meters? Lol

I didn't have my pinhole camera with me that day to take a picture with the cover on, so had to take the cover off for the picture! It was only off for seconds..promise.

That is a proper lash up and the question you must ask, is this a suitable means of connection as per manufacturers recommendations.

So, has the cover been adapted/altered to accommodate the extra cable? I wouldn't have thought it was manufactured to.

 

[jackhammerJIM]

That nut hasn't been designed for a cable termination . It breaks the regulation referring to manufactures instructions IMO.

 

[westward10]

See this all the time, how can I get another supply, I know lash it off that boards busbar. Legends in their own tiny minds.

 

[Andy-1960]

Looks like the lug is on top of the Bakelite holding the bus-bar in place which is also cracked.
Also why is it a red cable off the blue phase?

 

[Deleted member 9648]

I still cant think of a regulation it contravenes. Nor can I see any issues that may result from it being done like that. may not be the preferred method of connection but that does not mean it is against regulations.

 

[Andy78]

Would I do that ? No. But......
Is the connection mechanically sound ? Is the connection electrically sound ? Is the connection compliant with the regs ?
I would think a yes to all three based on the information provided.

I'm swaying with the OP's concerns here, the regulations are there to give you guidance and will not always detail specific scenario's but that does not mean it is then ok by default.
Looking at similar set-ups should give us an idea here whether this is ok and considering say a busbar chamber where you should not double up cables on busbar clamps as is normally stated within manufacturers guidance as they should each serve only one cable. Here we have a similar set-up when the bolt originally serves a purpose of clamping the busbars together and is not so designed to allow you to tap off although it has been utilised for this purpose, if it shows any signs of damage or overheating then I would bring it up as a matter for correction, if however it a sound connection and the busbar covers can be fitted giving the full protection level they did before then probably only worthy of a noting down. (I assume these busbars still have their covers).
