Pray tell, how are the risks minimised? Putting it into perspective, think of those who are not in the trade, only have one RCD and "No Lights". I can't be the only one to have experienced this!

So find the problem by turning off the mcbs and put the RCD back in.

An emergency light above the consumer unit is a bit of help ;-)

Lack of lights in a bungalow isn't a major risk in my book although in a 4 storey town house it may be.

What did people do during power cuts in the days before these new fangled RCD devices. They didn't all end up dead in the corner did they ?

No worse than a power cut Jaymack, so maybe the 18th edition will recommend that everyone has an automatic emergency power supply?

Now that sort of rule change could make us some money.

I inadvertently caused a bit of a problem with that idea once. My Dad lived out in the sticks and had a single RCD incomer setup - although the usual reason for loss of power was power cuts rather than RCD trip. Generally the (younger) neighbours would phone the supplier when there was a power cut (as they didn't always seem to notice). Thinking of my Dad's safety in the dark, I put in a cheap emergency light over the CU and another at the top of the stairs.

Power went off, neighbours - looked in at my Dad's and noticed that he had lights on - so deduced that there couldn't be a power cut and spend quite a while trying to trace a non-existent problem in their own installation while the supplier was blissfully ignorant of the problem with the o/h supply

OK for an informed person if there is no N-E or RCD fault!

Nonsense, most are behind closed doors!

Lack of lights in a bungalow isn't a major risk in my book although in a 4 storey town house it may be.

Stairs are not the only problem, e.g. think codger in the bath.

What did people do during power cuts in the days before these new fangled RCD devices. They didn't all end up dead in the corner did they ?

Not an argument but back to the future, we've progressed since then.

I don't see the reasoning behind this statement. We are concerned or should be, about reducing the probability of accidents caused when the lights go out ...... per se!.

How about retraining the population to watch where they're going and to take care if it's dark.
Although that would put a lot of the ambulance chasing lawyers out of business.

Customer dropped in a copy of the EIC and original quotation today.

EIC is dated July 2007.

On the quotation, dated May 2007, under the heading mains equipment, it says:

Supply and install one 12 way split load 100mA / 30mA consumer unit.

That puts a whole new light on it then! I wonder if someone has replaced the 100m/a rcd with a main switch, I came across one similar to this a year or so ago, in fact it was my sister-in-laws house that she'd recently bought. There was a split load board in place with 2 main switches fitted!

Dave.

It's not even a split load unit though Dave.
It's a 30mA RCD as main switch and 8 mcb's downstream, that's it.

No problems with being left in the dark then, due to an RCD tripping! But ...........
