Bonding in greenhouse

Alan B

On an eicr

I have a greenhouse connected to a sub DB in an outhouse, which is on a TT earth. Circuit is protected by upstream 30mA and 100mA RCD's.

I am debating in my mind if the frame of the greenhouse should be bonded to the single socket in the green house.

I would consider the frame as an extraneous part and therefore first reaction is to bond it.

But then thinking about it. bonding would reduce the risk of shock inside the greenhouse in the case of the socket became live but increase the risk of shock outside the greenhouse if the socket and greenhouse became live.

On balance I am tempted to go with not bonding, what are your thoughts?

    In a green house you may well be on the earth, but unless its a hippy commune, less likely to be barefoot, let alone naked and wet.

    But on the other hand, you're quite likely to have hand contact with metallic objects in good contact with the soil (e.g. plant supports, digging tools, staging) - often with damp/dirty hands, and if it's in an awkward corner, quite likely to be steadying yourself with the other hand on the greenhouse frame.

    So you may be kneeling on the earth floor and touching the greenhouse frame. No problem then, apart from falling over.

    The stats for electrocution ref. metal greenhouse frames are what?
