Completed a PAT course a good few weeks ago. I found it pretty strange as i passed with flying colours, but we done no practical, just had a demonstration. :roll: Sat thinking about doing some PAT for my uncle's office, when come up with some questions which i hope someone can answer, as no...

When it says points served on NIC forms, for lights does it mean one point = one light or does it mean if say 3 lights are turned on by one switch that is counted as one point?

On a 230V supply what is U & Uo? I Know one is 230V and other 240V but which way round?

So its just a case of giving them a PIR cert? It's just they rang today asking for a COC before returning supply. I had done a PIR for main contractor but supply was down due to fault. Fault was rectified but they want Coc before returning power, so if i leave a copy of PIR will that be sufficient?

How long would you say a new domestic electrical installation would last before needing re-wiring, in a normal environment? Its just a customer has an installation without CPCs in the lights, so obviously before 1966, needs a re-wire and wants to know how long a new installation should last.

But why round lights?

Why do flies, fly in circles around ceiling pendents? :evil:

But what if friend is unwilling to allow me to remove his tiles? Wher do i stand there? Do i write it as departure and explain in comments?

Upgraded it for a friend, i've done no other work at his house. He had no bonding to gas and a 6mm as main bond so i said i'd upgrade for him. He dosnt want me breaking his tiles to see if it plastic or metal

So how do i check to see if its metal? I put lead on tap and on stop cock to see if there was a reading but nothing, so presume plastic, is that ok? Can't i simply state this on MWC? Or say customer only wanted Main and Gas doing as Water would be to much mess for now?
