You been drinking steps?

Thats rather a silly question isnt  it?

You try reading one of Steps posts that hes made when hes not had a drink, they're the incomprehensible ones.

My mistake!

Steps go have a drink and retype the post!!

What worries me is someone saying 133Ω is “within guidelines”. Which guidelines?

 

[Sidewinder]

BS 7430 Tony.

Code of practice for earthing.

OK I’ll give you that one kid.

But would you be happy with it? I wouldn’t, ≤1Ω = a happy Tony.

As you know I’m more accustomed to the foibles of DNO’s

I prefer double figures, at least on anything, but, in the private sector doing work for paying customers who don't really want to pay, it's always an economic trade off.

So, if you can meet 7430, then the job's a good 'un.

The general "guidance" for a 1ph install up to say 100A is < 200 Ohms.

Now, that is limited to just this.

It doesn't apply to anything > 100A, so then you need to go to 7430, and greater details.

A LOT don't bother because they don't understand.

A lot (most) don't know what an Ra test is.....

:slap

they just test next doors earth instead with their Ze

I'm really confused here, are you saying the the Ra of a TT installation should be <200 Ohms if the supply is under 100A but it can be 7430 Ohms if the supply is over 100A?.

 

[Marvo]

Ahh, thanks.  I nearly had a cardiac arrest when I thought he may be advocating a 7430 ohm Ra. :coat
