16amp from 13 amp transformers

Have you got a link to these? It seems unlikely that its possible because of the laws of physics. Given a fixed voltage supply (240v) To achieve a higher current you would need to reduce the output voltage of the transformer.

Simplisticly, Power = Current x Volts (P = I x V)

so for 240v and 13A: P = 13 x 240 = 3120

therefore to achieve an increase in current to 16A, treanspose the equation to P/I = V: 3120/16 = 195v

So to achieve the 16A output and not draw too much power from the mains ring would require a transformer to give an output of 195v (assuming the transformer is 100% efficient which it won't be)

Your best and safest solution would be to run a 30A spur from the main fuse box and use that.

That is a step up transformer the converts 110v to 230v. The two 16A outlets will only provide that level of current if the input has sufficient power to do so. Being a 110v input its going to require prbably about 60A @ 110v to achieve this. Either way, its not going to do what you want.

Unfortunately you can't get something for nothing when it comes to electricity!!

Thanks all , I will get it done properly 😀

Don’t know yet Nick, haven’t actually bought one, and since I’ve just broken my arm it might be a few weeks yet! 🤣

Just to clarify, that is not a domestic outlet rating but an industrial outlet rating. A domestic ring from the consumer unit is rated at 13A with single spurs from the consumer unit for individual items such as cooker, shower and immersion heater rated at 30A.

My father used to have a single phase lift that was rated at 16A just plugged into a socket in his garage. The problem was the initial start up. sometimes it would trip, sometimes it wouldn't. Once the motor was running it was no problem.

It mostly stems from the fact we have ring mains in the UK, which will be fused at 30/32A. We then have fused plugs to protect individual appliances.

I believe most of Europe install radial circuits to each point. We rate our radials the same at 16A as everyone else, but don’t install them normally.
2 2.5mm cables sharing the load in a big circle, ring) can carry twice the current of a single radial cable, hence the 32 and 16

A 13A plug top is obviously rated 13A, but there is a duty cycle, so it’s fine to pull 13A for a few minutes (like you do when you boil a 3kW kettle) but you’d overheat the fuse if you were drawing that current for a long time, which is where the problems begin as you can then cause damage which causes more heat, which causes more damage etc

As said, probably the best thing to do would be to install a radial with a 16A fuse. If you have a dedicated supply to the garage it wouldn’t be hard to do at all

Just wire in a 240v 16 Amp 3 Pin MK Commando Surface Appliance Inlet - Blue - IP44
Either off your 30A ring main or run a separate circuit if its easier back you your distribution board using a 16A breaker.... NO transformers needed as they transform volts not amps.
Simples and how do i know ? I'm an electrician and run my MIG welder off a 16A plugs.
You can get a 16A socket complete with a built in switch if you prefer, just type 16A plug & socket into Google
2.5mm cable will easy take 16A as long as the run is not very long.

Sorry, you are correct.

Was just trying to describe it as simply as possible

It will not do any damage as the trip would go out in Milliseconds,  you run your 13A appliances off a 30A circuit in your houses and most of the time very few people have the correct fuse in the plugtop. Plus a fuse does not give the correct protection against some faults and is also not quick enough hence modern circuit breakers.
How many times does a fuse go before a trip ?  
But if you really want a belts and braces approach put a switch fuse or Trip switch before the plug or even another solution If doubts remain, how about installing the 16A socket that have a modular DIN rail enclosure as part of the housing and adding a local 16A MCB or fuse?

As i "said" its better to run the circuit on its own back from the distribution board if possible with the correct C/B protection, but that's not always possible if there are no ways spare in the Distribution board hence taking a feed off a 30A cirtcuit like a Ring main . The cables are big enough and you can fuse or C/B down if you wish. like any other spur off a ring. As you are allowed one spur for each socket on a rings main, but i don't recommend that.
