Busbar - 1.2MVA generator install -

mikeruss

Hi all

I hope you can help.

In short:

I think I am being spun a line from my supplier.

I am contracting the installation of a 1.2MVA generator (outside the building), and my supplier is claiming new regulations stipulate a busbar must be used instead of the normal cabling to run to the building. Of course it's more expensive, bigger trench etc etc

It's a complicated relationship, and therefore difficult to get other suppliers involved.

The questions I have are:

Are there new regulations that stipulate a busbar must be used irrespective of generator output?

Assuming there are no reg changes

What is the maximum distance you can run cables before you need to use a busbar.
Is there a benefit to using a busbar over cable?

Thanks in advance.

ditto benji, we need more info to see what the choices are.

Are you hoping to cable a long distance? would it need parralel feed cables and does this make the BB more viable?

I haven't heard of anything relating to a must for BB use in this situation
