Nema 6-20R Recepticle Compatibility In The Uk

[toffeetop]

Hi Guys

I am a complete dummy when it comes to electricial lingo so please excuse my ignorance. i hope you can help with a problem i am currently having.

i have recently bought an instrument that is breakthrough technology for Cancer Diagnostics in the uk, however this is an American instrument and comes with the following requirements

• Dedicated/Isolated 20 amp Circuit.

• 230 ± 10% Volts nominal AC, 50/60 Hz - NEMA 6-20R standard receptacle

• Ideally, power will be provided from an uninterruptible power source

I plan to link up a 10KVA UPS to a standard 13amp UK receptacle then from the UPS attache the 6-20P plug to an adaptor (with UK 3pin and 6-20R functionality) would this work or am i missing somthing realy obvious. i dont want to have a situation where i do not have enough power or short the adaptor or worse blow up the instrument as it costs £130k.

any advice would be greatly appreciated

Given the price of the instrumentation it would be a shrewd idea to contact some professional help with both the plug and the specifying of a decent UPS that will offer you some surge protection.

Well the NEMA thing is an American 3 pin  socket ......I don't see any advantage in using it to be honest  but if it costs £130,000  I guess you should follow manufacturer's instructions.

HI Guys

Thanks for reading this. the plug is hard wired onto the  intrument so i ahve to use it unfortunately its just getting the socket. the UPS is a DALE, i believe these are good. do you think this will work?

Well unless I am missing something somewhere......

it requires a dedicated 20Amp supply

you want to connect it to a 13Amp supply

you alsso want to poweri it from a 10kVA   UPS

these numbers  do not match up.....you need to know from the UPS supplier what their Unit will draw when your load is applied since their kit will have its own inherrent loses

Hi kerching

I asked the UPS providers and they said it should be OK but to be honest i wasnt convinced. It is my understanding, and please correct me if i am wrong,  that the 230V supply from the standars UK sockets should provide enough power, with the UPS providing surge protection, am I badly wrong

1  should ?

2 should ?

3 are you sure?

you really need to get a professional in to sort this for you,

as has been said, at 130k is it really going to break the bank to seek some professional help to install it?

230 Volts  is the 'carrier'. The Amps are the 'power' and a standard socket here is 13A, but your equipment is 20A so you will be overloading the circuit

 

[toffeetop]

thanks all. as a temporary measure, can i use the 10kVA UPS to draw power from? if the UPS is connected to the mains and will recharge during inactivity. Also the instrument has a nema 6-20R plug, if i was to use an adapter would it be possible to change the adapters 13 amp fuse with a 20 amp fuse?

something strange about this post !! anybody installing such equipement would have to be fully qualified and on a approved list of installers possibly NHS would have some input as well

A dedicated 20amp circuit is not a standard 13amp socket outlet. As by your own definition you are a complete dummy, the correct solution is employ a professional to do the work for you and ensure that manufactures instructions are followed. i.e. if it is asking for a 20A dedicated circuit do not use a supply that is 7amps short of manufactures requirements. Either listen to the advice, or just go and plug it how you like and see which bit melts first.

And remember, NOT everything made for mainland UK will work in NI,

I remember fiasco a few years back with storage heaters, bearing

so, if his machine is sensitive to supply you really need to understand its requirements before connecting it to anything,

Remember, it needs smoke to work, it will stop working if the smoke leaks out.!

H guys

Thanks for all your advice. Just to add a little more background on myself: I am a distributed for this company and I had to buy it in for a trial in the NHS, my questions were relating to a site survey, which just so happened to be the wrong one that they sent me, (USA placement as opposed to the uk requirements) so I have been told that it will run off a 13amp circuit and has UK plugs so I should be ok now. Again thanks for the education.

Doc H : I thought the one of the roles of a site moderator was to prevent potential altercations, might I suggest you keep this in mind in your reply to other dummies?

toffeetop ,

you and your suppliers do realise the electrical supply for norn iron is different to that supplied to the mainland UK ?

it can be quite significant for stuff such as this to either not work at all or just go bang.

Hi Steptoe, what is the difference? Nairn iron

 

[steptoe]

been a while now toffeetop, NIES or whatever they are now will spec you their supply,

a few years back dimplex [or whoever] went on strike in ireland and we couldnt get storage heaters cos the UK ones tripped out continuosly with NI supply, there is deffo a difference,

not a lot of stuff matters, but just make sure what you are installing is OK.

remember, most far east kit [tv's etc]will run on half a dozen car batteries, not so for precise electronic kit.
