Double socket power help.

[maxheadroom123]

Apologies if its a very basic question and I get the terminology wrong.

I have an air fryer which is rated at 1800W I have this plugged into one side of a double socket my PC is also connected to this socket by way of a two way plug adaptor.

We bought a deep fat fryer today which it turns out is rated at 2100W I never give this rating and maximum power output for double sockets a thought until I was half way through cooking tonight using both machines, I hope I haven't messed up and its safe to use both at the same time as my kitchen is very small and I really don't have anywhere else to put both machines.

I look forward to your reply and thanks in advance.

The maximum rating for most 2G sockets is 20A

Dont forget you'll have both of the thermostats cutting in and out, so the maximum load of 16.25 amps with be varying all of the time

Thanks to both of you for the quick response.

I have the same question posted on another forum as i was getting worried and didn't want to use the new fryer again until i knew it was safe, they explained how to work it out but i forgot to add the 500w for the PC -

1800+2100=3,900
3900 watts divided by 230 volts = 16.96 amps.

So if the PC was running flat out would it be totally safe to be so close to the maximum rating even if only for 15 minutes once a day at tea time when the fat fryer, air fryer and PC are on at the same time?

The PC has a 500w power supply but to be honest its only ticking over most of the time as i no longer game on it.

1800 + 2100 + 500 = 4400

4400 ÷ 230 volts = 19.13

230 vac is the 'new' stated single phase voltage when in practice it is usually hovering around 240ish as it always used to do. It is quoted as 230v for EU harmonisation, but in reality, nothing has changed.

Thanks Sally.

Could you put my mind at rest, if i am using - 1800 + 2100 + 500 for 15 minutes once a day at tea time when the fat fryer, air fryer and PC are on at the same time have I nothing to worry about?

You are worrying about it much more than the average homeowner would. I will be fine.

16.46 amps for 15 mins should be well within the capabilities of a twin 13a socket and not cause any problems.

The test current is 14A for a single, 20A for a double (14A + 6A), and the duration is 4-8 hours.
Maximum temperature should be no more than 52ºC.

Sorry I thought it was 19.13 have i got this totally wrong?

1800 + 2100 + 500 = 4400

4400 ÷ 230 volts = 19.13

Also the 500W relates to the output power of the power supply, not the consumption.

Thanks I didn't know that.

I am that sort of person, i am looking forward to having a beer or three later and forgetting about this for today

Also both heating loads are resistive so are definitely voltage dependent. The lower the voltage, the lower the amperage drawn. Your house voltage is changing all of the time so calculations are basically averaged out depending on the voltage at the appliance for any given time.
Just being curious I've checked my voltage at a kitchen socket and its hovering around the 244-7 mark without any loading on that ring circuit. As soon as it's loaded up that 244v could drop all the way down to 235 or maybe even lower. It does not bother me in the slightest.

Thanks everyone for the great answers which i am sure will help other people like me who haven't a clue and may worry needlessly.

All fine in theory, but check the socket's a decent one. For the sake of a few quid you can change it to a new one, checking the terminal screws are nice and tight while you're at it. MK sockets are generally about as robust as you get.

I once had a kettle plug weld itself into the socket. All BS-whatever marked, all fine in theory, in reality maybe not.
