We've used one from RS components, was around 70 quid IIRC

You just reminded me I forgot to fetch their new CD home tonight,
thanks.
Do you have a part No by any chance Tony?

Hi Andy,

I doubt that the supply authority (distribution network operator, or
whatever they're called this week) would accept that. (You do realise
that you're supposed to liaise with them?)
No I didn't thanks. May be worth a call to them to see what they would
expect to see in the way of protection.

You'd need two contactors and it would only need the contacts on the
mains feed one to weld closed for your genny to be capable of
back-feeding the mains... A conventional generator change-over switch
is much safer and more straightforward bet.


Is a conventional change over switch automatic or manually operated? I
was looking at a contactor as that is what is in the control panel of
the genny at the moment, unfortunately it is only rated at 40A, it came
off a remote radio site and only had to back a fairly small load and so
didn't warrant a higher rated unit.

The difficult bit these days will be getting through to someone who
understands what you're talking about. Contact the distribution network
operator for your area, not the supplier who sends your bills.

I had the manual type in mind.

They'll probably be happy with a proper changeover switch with a fool
proof break before make action. This is normally arranged by having
the a 3 position switch with a center off. Indeed this makes sense
from safety point of view as you can the ensure that the supply
onwards is really off. Just in case you switch it to "generator" to
isolate then some bright spark starts the genny...
