I do have my little saying about Bulbs v Lamps but it is rather tongue in cheek though - sense of humour type thingy.
For what it's worth, I used to use the terms 'bulb' and 'lamp' interchangeably in my youth, until around 10 years ago.
I worked in a high school where all our projectors were hitting a certain age and the lamps were dropping like flies.
The replacement 'lamps' as many of you may know, were hideously expensive:
However, we learned we could buy just the 'bulb' separately and transplant it into the frame that makes up the replaceable lamp unit:
Saved a ton of money doing that.
Ever since then, my understanding of the term changed slightly and I came to use the term 'bulb' for any type of light source with a glass envelope (i.e. a typical 'glass bulb'). However, I tend to use the term 'lamp' for a fluorescent tube, so perhaps I contradict myself there.
AM and PM as I`ve mentioned previously - oohh that winds me up with a vengeance.
When people say "3AM in the morning"... I can't let go of that one.
What else would you be referring to? "3AM in the afternoon?"
PAT Testing and PIN Numbers - yes I mentioned them before (and a few more).
It does wind me up when the term 'PAT testing' is used.
However, I've given up correcting people, and sometimes just throw the term around myself for ease of conversation as the alternative is to say something like "That device needs PAT'ing..." which causes a great deal of confusion from other participants in the conversation.
You didn't need to extend the ring; it is permitted to place the FCU at any point on the spur - the cable - but then obviously the spur - the cable - has to be connected to the ring by other means.
I recently added a Fused Connection Unit in my living room for an electric fireplace.
I extended the ring to include this FCU for two simple reasons:-
1. It was easy due to the proximity of an adjacent double socket
2. I hate trying to cram 3x 2.5mm cables in socket terminals - I found this much easier
