Electrical Certificate

[ryanj]

Quick question,

Would two consumer units (2x12, circuits split evenly between), warrant two installation certificates, or will one suffice with all the circuit details on it?

Also, does anyone know the purpose of the cream functional earth tail on the MK RCBOS?

i belive it powers the pulsating dc sense curcuit in the event of a lost neutral fault

I would probably go for two certs. Partly because the Ze value may be different for each, depending on the length of tails and suchlike and also because of possible confusion with circuit numbering. For instance, are your circuits numbered 1-12 and 13-24 or what? And, depending on which certificates you use, are there sufficient rows on your test schedules to include both on one schedule?
