Plugging an Extension into another

TheVoid · 15-12-2013, 15:54

Hi, I have a 4 way power adapter which is a decent one with surge protection. I've had to plug another one into it so that I can have my TV where I want it (I need 6 sockets behind the tv).

Is it safe? I only have 2 plugs into the 2nd extension, but I was desperate.

Or is it best to get one of these -

I have the 4 way one at the moment. Not sure what to do.

Thanks.

Yes, no problem as everything is fairly low current (don't go plugging heaters and kettles in though.

Really? All at one plug socket at the wall?

I was worried about overloading? In one wall socket, there's a 4 way adapter which has speakers, TV, Sky Box, and another 4 way adapter connected which has a PS4 and a PS3 connected to it.

Add up all the wattage of everything plugged into the sockets and if it's less that 3000W then you'll be OK (assuming a 13A rated extension lead). My guess is that you'll be much less than 1000W with a tv, sky box, dvd player etc. A big 5.1 amp is only about 600W at full pelt.

Indeed only the amplifier is likely to have any significant load. A 3Kw amplifier would blow out your windows

TV maybe 100W, Sky Box 40W, DVD player about the same.

Yes really!

As I said (and others have expanded) the loading is only VERY small - you could run more than 30 TV sets off a single 13A socket for example.

The BIG users are heaters and kettles. Some modern vacuum cleaners are pretty thirsty as well, but still well under what a socket can supply.
