BC to ES adapter

[Dave Plowman (News)]

If someone doesn't know the implication of a two way switched circuit, then best to leave the bulb changing to one who does?

[Roger Hayter]

Strangely the sort of people who say this are precisely the sort of people who sneer at the NHS (and other large organisations) that do not allow their staff to change light bulbs without calling in an electrician. I blame the Daily Mail.

For real. I've seen a sign in the local hospital which read "Light Bulbs are only changed on Mondays". Once the hospital would have had its own electrician(s). Now it uses the cheapest outside contractor it can find.

But they would have to know about the implication in the first place before making the decision to do that , as far as they are concerned turning off the light has made it bulb holder safe. Many will never have heard of two way circuits ,the lights just work and go off when a switch is used.

It's a bit like you going to dig a hole in the garden and finding you yourself falling into a long covered well you did not know about. I could imply you should have got an expert in because you did not know about the well and were only concerned with planting some bulbs (the other kind).

So why didn't you say that.

You might know the "implication" of two way switching, but not know which switch positions mean "off" if there is only one (blown) light in the circuit.

[Dave Plowman (News)]

Really? No danger of them shorting together?

But is there any real evidence of a BC (or ES, come to that) bulbholder being a real safety hazard? Before insisting on a total re-design as some here seem to want?

If you go to change a mains bulb of any sort and it doesn't come out easily, surely the obvious way is to make sure the circuit is isolated before going further? Same as with anything electrical?

[Dave Plowman (News)]

They may not know what it's called, but only a total idiot wouldn't realise either switch makes the light come on or off. Must be several of those on here.

But the rule is the same. If you don't have the most basic understanding of how something works, how can you expect to fix it?

[Dave Plowman (News)]

So best to just gamble, then? Is that your answer?

[charles]

I had "fun" removing a BC base from SWMBO's desk light. The usual 'push in and twist' left me holding the glass bottle. Eventually got the base out with an assortment of pliers, but I had to dismantle the lamp first to gain access to the BC base.

[tabbypurr]

not when one is bare, the other single insulated

no

I think you'll find most people don't know what isolated means. And really changing bulbs live is not a problem.

Plenty of people didn't realise there was a second switch, or just forgot. It's not restricted to idiots.

Can you really not answer that?

[Max Demian]

What's your answer? To flip the MCB and change the bulb in total darkness and annoy other residents of the house? No, but I'm quite capable of changing a bulb without sticking my fingers in the lamp-holder, and would only be slightly surprised if the light came on immediately.

[Dave Plowman (News)]

If you are stupid enough only to have only one lighting circuit, then yes. If you prefer to be safe rather than sorry.

Think most people are capable of changing a light bulb safely even with the circuit live. Those that aren't will blame anyone but themselves if things go wrong.

[charles]

What's wrong withn using a torch? A head mounted one is ideal.

[Clive George]

I'd not have a problem doing that if necessary. If I'm mending the house by changing the bulb, the other residents can put up with a couple of minutes of darkness in half of it.

When I wired my house I put the hall lights on a separate circuit. That gives enough working light to change a bulb in any room - and vice versa.

[Dave Plowman (News)]

So just about long enough for UK makers to catch up with the need for ES fittings?

Since about the early 80's I reckon.

Er, no, small BC dates back to at least the early 60s

The Euro and American ES are different sizes. E26 in US and E27 in Europe.

R80 spotlight bulbs come to mind.

all the rage now, and I always liked the decorative ones

Nonsense. Go look at the bulbs on display in any supermarket, hardware store or pound store

we've already adopted it. Get over it.

Your post sounds like you're in a time warp from 1970.
