Yes.. but where can I find them..?
Niceic shop only has certs for grade b,c,d,e,f systems..
I can't see any online that state suitable for grade a.
The system as installed to me is a Grade a ld1 system.
Why are all the certs I can find not applying to grade a systems?

Yes we programmed the panel on site.. straight from the panel..no need for any extra gear .. tested with canned smoke ..
The smokes in each flat are in the hallway not the kitchen area so toast shouldn't be a worry.

Hi all

This morning the customer rings to say the shower has tripped the rcd.
Turn up on site..and the rcd that has tripped is not the one that the shower circuit is on.!

Must stop drinking red wine on Monday nights.
Ajshep.. Yes just looked these europa ecpf05 .. I don't believe there is any protection apart from a 3ph mcb for each heater ... but I...
Thanks for that contact.
As I said they appear to be of the type sold by RS ..
And looking at the rs wiring diagram they may or may not be suitable for delta connection depending on the part no. So far I can see none.
Maybe I should introduce a neutral. .. to the star point ... but there is...
Good stuff gigsy. .. we don't want rule of thumb ..we want to know why.
If there is no reg that's has been broken then any problem is the iee problem .. not ours.
Brian Moore .. good stuff.. Plymouth. .?
OK I'm still not sure about star without a neutral.
I understand that they may not be designed to have 400 v across them ... but maybe they are ... but I can't tell without a part numbe ..I see from rs that some are and some arnt .
But I guess in the end it's in star now..it works..with no...

I gather it started and ran at full speed from new.
But always hot by the sound of it...the customer promised he did not ever overload it...light use only once or twice a month. ...strangely on this occasion I believe him.
He removed and replaced the...
