I did!I sometimes wish I'd gone into teaching!
Steady money I would have thought, my ex-wife worked as a lecturer at a college in Luton she was on good money.I did!
Technical collage - electrical engineering and electrical installation
Left it rather quickly - hated it.
It wasn't for me, I pretty much gave up after dealing with one student, he was useless at anything technical - but was in an onc technical stream.Steady money I would have thought, my ex-wife worked as a lecturer at a college in Luton she was on good money.
I'm 8 weeks into an apprenticeship and haven't covered it at college yet. Thought MCB's were for overload protection (whatever causes the overload) and no protection to people being shocked because it says it on several sites i've read, and that RCD's were solely to protect people and not equipment.Is it just me or has this thread just revealed a tragic lack of understanding between fault protection and overload protection? This is basic stuff ladies and gents.
true, but a MCB downstream of the cable(SWA in your case) cannot protect the SWA if it were to short out for any reason. the MCB can only protect cable downstream of itself.I'm 8 weeks into an apprenticeship and haven't covered it at college yet.

I know that, my question was based on the OP claiming that the cable could potentially pull 80a. I was asking how can it when the only thing actually pulling any amps (in the absence of a fault) has an MCB that won't let it pull anywhere near enough to create a dangerous situation?true, but a MCB downstream of the cable(SWA in your case) cannot protect the SWA if it were to short out for any reason. the MCB can only protect cable downstream of itself.
just imagine a kitchen fitter screwing into the SWA before the MCB. it should be OKas he'll wrap some tape round it. ??I know that, my question was based on the OP claiming that the cable could potentially pull 80a.

It's a case of crossed wires in this thread but too difficult to iron out over text so best to leave it there.
I know that i was literally just asking about the OP's assertion that the cable could pull more than it's rated for which in the absence of a fault i didn't think it was actually possible at all because of the MCB protecting whatever is drawing amperage through it.just imagine a kitchen fitter screwing into the SWA before the MCB. it should be OKas he'll wrap some tape round it. ??
