Can anyone tell me what the load (number of plug sockets) I can safely run
on one 30A domestic ring main? Is there also a limit of light fittings on
the lighting fuse?
Cheers,
Carlos.

There is no limit to the number of socket outlets on a domestic ring main as
you never thoereticly run the max (32a) on a circuit in appliances. If
however like most households nowadays , you find there is a lot of heavy
load appliances ie washing machine, dish washer, tumble dryer, kettle,
toaster, etc. that will be in use together it is advisable to install a
seperate ring main to the kitchen area or split the upstairs and downstairs
into two circuits.

I think the recommendation is that each ring main serves a certain maximum
area.
Cant remember of hand what its is. If you do over load it then providing its
wired correctly, with the correct size wire and fuse then you simply blow
the fuse and learn your lesson - bit late though
if you must have all these high power appliances plugged in !

As for lights, dunno. I suppose as long as the total wattage does not exceed
1200w (i.e 5amps)
your ok ?

I was at a meeting last week where the organiser had plugged two
kettles into a 5amp extension lead.

Melted insulation is such a chore to clean off carpets.

But why didnt the fuse at the consumer unit blow and protect the wiring ??

Oh I see ... an extension lead. Should have had a 5 amp fuse in the plug
then !

Well, actually it was rated 10amps when unwound, 5 or 6 amps wound -
and it was wound. 13a fuse...

It has been one of the bees in my bonnet why that new wireable plugs don't
come with the LOWER 5amp fuse and if you NEED to put higher you have to put
10A or 13A fuse in rather than having to know, that you have to put lower
rating to to match the wattage and save the wire and fit a smaller fuse,
most people are not fully knowledgable and sometimes lazy, if they buy a
plug they think the expert has put 13A in because this is suitable and that
is correct for all applications,

why provide the fuse at all, then people
would have to buy a suitable one.
