Power Overload?

tbh I assumed it was a spelling mistake, now I assume you need to get out more.

The second post addressed the wider issue of the standard domestic ring main and followed on to earlier posts which intimated to some designers view that adaptors/trailing sockets should not be made available to the uneducated general public.

There's nothing wrong with trailing socket extensions as long as they are fused.

Fuses do not always prevent fires.. just ask your local fire officer!!!

A correctly rated fuse will prevent a fire due to excessive current in the wiring it protects. It won't stop arcing on a bad connection. Nor will it stop fire in things plugged into the sockets if they are not safe items themselves. Therefore it can't prevent all fires, but for the purposes of this discussion it prevents fire due to an overcurrent condition in the house wiring.

[/quote]fuses are a safety device NOT I repeat NOT a failsafe.[/quote]In what way are they not a failsafe? They cut off supply when too much current is drawn.

Knowing how much equipment you can safely plug into all the sockets and use at the same time in your home should be taught in schools.

It wouldn't be useful. Do you know how many sockets you have on each ring main in your house? No, don't start looking around the house, I mean off the top of your head. Of course you don't. It isn't important. Do you know what current any other members of your household are drawing at any one time? Again, of course you wouldn't. Only the breaker/fusebox should care.

and a further thought/ observation.........very soon the time will come when devices plugged in will "be seen" by a microprocessor embedded within the domestic consumer unit that will monitor and control the whole circuit as the designer intended. This will clearly annoy some consumers who feel thier "rights??" will have been stolen?..

Another step in the nanny state or an absolute necessity....Discuss?

Lunacy. In what way are circuit breakers insufficient?

Just buy one of these

with respect that's your view, but not shared with everybody

Are you referring only to the BS 1362, what about tolerances?

In what way are they not a failsafe? They cut off supply when too much current is drawn.

I was referring to "failsafe" as a particular device, have you watched a standard cartridge performance on the scope?

untill such time that the consumer unit becomes more "intelligent" then I do not think that is a bad thing at all. Have you ever actually seen what some people get up to. As for knowing what is happening at my home, yes I do know what is going on for the most part. I am very fortuneate and own equipment capable of allowing me to monitor such real time events. You would not expect anything less would you?

I'll take that as a vote for no then shall I, How long do you think it is going to take for sophisticated industrial control gear to move into the domestic market, what never? The more electrical/electronic goods appear in our homes the more demand there will be to legislate against irresponsible use.

Even you admit you haven't got a clue what your configuration is, what is more concerning is that it would appear as if some people posting here don't give a damn and worse dont want to know.


Just buy more goods and plug them in ..... the fuse will save us all!!.

Imagine how you would cope if your whole supply from the grid was reduced to
10A instead of 100A . You might want to know then maybe.

Now thats my kind of solution. every home should have one:D

in fact I have two! and a giant fire bucket!! and a blanket in the kitchen :rolleyes:

Talk about over complicated answers for a fairly simple question.

Power overload - no

Ok to do - yes.

Duncan303,
The OP has an extension lead plugged into a double socket with what appears to be about a 800 Watt load.(Your estimate - I would have estimated 500 Watts)

She wishes to know if it is OK to plug anthe extension lead into the other socket with a load of about 250 Watts.

The answer to he question is very clearly in the affirmative - would you not agree?

She is clearly aware that there can be a problem if extension leads/sockets/ringmains are overloaded or she wouldn't have asked the question.

Do you not feel your posts have over-complicated the issue just a teeny weeny bit?
