Mains 10-way socket,causing power cuts?

Mar 06, 2005 28 Replies

Hi there,



Recently I installed a maplin 10-way plug extender, with surge protection. Cost £24.99 and was the only one that had 10 sockets, which i use, but not all at once.



Anyway, it said on the box 'don't plug directly into the mains' - i take it that means the main mains power source in the house, i've plugged it into a socket in my room - has a few bits and bobs.



I'll be honest, it says 'dont have more than 13amps on it' plug-wise, i've prob got more than that....



Today i was hoovering through *another*socket in my room, and we had a power-cut, i think it was in the entire house but i can't tell as nothing was 'on' that would indicate so, but everything in my room cut out.



I don't want to blow up the house, but surely if it says 10-way socket expander it *should* be ok, even with more than 13amps going through it?



It's a comptuer, video,tv,printer,monitoramplifier and a couple of other minor things like wireless router.



I don't want to damage the house.



Indicentilly, we had one 4 way extender plugged into another one that was plugged into the wall, and it's been fine for 2 years - but i finally realised how dangerous it potentially was and thought i should splash out.



Maplin only sell the one 10-way extender, the rest are either 2,4 or 6, which wasn't enough.



Any suggestions/help anyone?



Cheers!

is the item - for all those who wish to have a look....cheers!

What do you mean by a power cut? Why can't you tell what was cut - are you saying the power came back on by itself?

Er - why would you think that?!!

What other "minor things"? That doesn't sound like 13A so far - where do you get that figure from?

By a power-cut i mean everything went off in the room i was in, the hoover on the one socket itself, and the 8/9/10 sockets on the mains-extender which was plugged into a socket the opposite side of the room. Then everything came back on.

Later on the computer restarted twice, along with other items powerong off then back on, so i believe the extender to be the cause.

Also, i don't know what you're thinking of, but how can 13 amps not be achieved already?!

A monitor has a high-fuse, along with the amplifier surely, and the television. In fact it would be piss easy to go way over the 13a thresh-hold.

If you think about it there's actually a far higher chance of attaching 10 items to it and going over 13amps than NOT going over it - you could have no items rated at 13amps, one at 3 amps, and nine items at 1amp - that's a bit s**te isn't it?

It's the only 10-way-extender i saw in maplin and 2 other electrical-specific-parts retailers, so i guess that is why.

Nothing to do with the mains extender then, if the hover was in another socket then it can't be that. Nothing, (unless you have some rare industrial control system as a CU), will be in your wiring to automatically reset the fuses\MCB's in your CU.

Anything else in the house?

What?

I think you've got the wrong end of the stick. If an appliance has a

3A fuse, it means it draws less than 3A, could be 0.001A. I've got a TV, amplifier, CD player, DVD player, various other boxes of musical orign, 2 STB's and a Quattro switcher. I haven't got it to 3A yet.

If I add a PC I still won't be anywhere near 13A.

You need to check the actual rating of all the appliances you have plugged in, not the fuse sizes.

What the f*ck are you on? Just because you have a 13,10 or 3 amp fuse DOES NOT MEAN the item will draw that current. The fuse just protects the cable from overload. To find the current drawn, have a look on the back of your equipment and read the plate where the voltage and current will be specified.

Oh well apologies to the aforementioned poster! I was told to check the fuse by a maplin attendant! It was a bird tho, so maybe that's why.... har har, just kidding ladies...

I don't know how to check the 'amps' of the appliances, the back labels say nothing relevant!

I have a freeview box, a small portable television, a video recorder, a printer, 19inch computer monitor, high spec PC (medium wattage im guessing) an amplifier, a light, and a wireless router. All ten sockets are used up... i'd guess 13amps are well used up?

Hardcore drugs...

The back of the video says 67w... No 'maximum amps used: 500 mAmps' like on the printer adapter....

Argh so rubbish and hard

Did the OP say another socket in the room went off ?

Implies something loose in the back of the one with the 10 way in it (and the other one being a spur off it, not off the ring)

I am the OP :-D

Excellent.

I was wondering how the sockets were wired up.... it's an old house as well, and the sockets are blatently old. I may get an electrician in; although it's possible the neighbourhood had a powercut a few times during the day - but unlikely i'd suggest.

Watts = Volts x Amps

therefore Watts divided by Volts is Amps

Assuming you are in the UK, 67 / 240 = 0.28 Amps

The bottom line is all the electrical energy you get from a socket turns into heat in the room.

13 amps is over 3KW - which you'd probably notice.

The one exceptional circumstance is the switch on surge of electric motors etc. 3 fridges on the thing /might/ blow a fuse if you switched the 10 way on with all 3 plugged in.

The key thing here is it DIDN'T blow a fuse.

What I would do is plug something robust into the 10 way and the other socket - a couple of lamps maybe ... and pull on the 10 way slightly.

As I said in my other post, It's my guess the wires in the back of the socket are loose.

You don't sound very /au fait/ with things electrical so I'd advise you get someone else to take a look at it (and maybe the rest of your wiring)

Current = Power/Voltage = 67W/240V = 0.28A (ie 280 mA)

David

Watts=Volts X Amps So that 67w appliance takes about .3 amps

sorry that was a bit fuzzy but I'm ready for an early night :-)

Nowhere near!

Probably a total of just over 1000 Watts if everything was switched on - or around 4 to 5 Amps.

The handbook for each piece of equipment should give the power usage figure

How old is old? Are they round pin or square?

Listen mate, you're in no postition to talk!

re-reading it, actually I bet it's the other way round - the hoover's probably plugged into the other socket on a regular basis and the cable gets tugged ...
