US 110v equipment for UK use

[jaffy1229]

Ok I was emailing someone on the website but I think he just confused me.

There is a step down transformer on their site but I can't work out if the wattage is high enough for the appliance

Here are the figures:

Truecoat Wired Electrical Requirments Specs: 20 Vac, 60 Hz, 15A, 1 phase
TC750A Step Down Voltage Converter 240 Volt to 120 Volt. 750 Watt Maximum Capacity

Can someone confirm that this converter will be compatable with the Truecoat appliance?

Thanks!

For the appliance you've listed 20Vac, presumably this is 120Vac?

I guess it must be. I just checked another site and it states the Power Source is 120VAC

Looks from their site that the thing takes 4A when running. I think the 15A refers to their plugs. It probably takes more than 4A to start up though and that's the unknown - will it start up with a particular lower rated transformer?

BTW volts x amps = watts

I would expect any plug in equipment for the US market to have double pole switching for the same reason most european equipment I've seen does - they have non-polarised plugs so either wire can be live. Of course, what I'd expect for safety isn't necessarily what the manufacturers make !

The US uses 3 pin plugs for non double insulated equipment and are obviously polarised. Modern 2 pin plugs are also polarised, one blade is wider than the other so will only go in one way. They won't fit older sockets at all.

Caution The Live in american flex is BLACK and the WHITE is the neutral.

I found some more technical data on this appliance which refers to the electrics:

Trucoat Maximum amperage is 4 amps
Truecoat Wired Electrical Requirments Specs: 120Vac, 60 Hz, 15A, 1 phase

The transformer states a 750 Watt maximum capacity.

So 120x4 = 480

I assume this Truecoat sprayer is 480 Watts and the transformer can handle it as it is 750 Watts?

Can someone confirm this is right? Thanks

Does the transformer specification say 750 watt continuous ? In many trandformers designed to power hand tools the maximum quoted is for intermittant use. If there is any mention of duty cycle or similar then 750 watt continuous load may cause the transformer to over heat,.

For your application ( ignoring any effect of the lower frequency ) the 750 watt transformer should be OK but if there is a duty cycle of less than 50% then ( rough guide ) the countinuous safe load is 50% of 750 watts.

Many yellow brick site transformers burn out because the duty cycle has been exceeded with maximum loading.

I just had a look at the webiste and found the specs:

Model: TC-750A
750 Watt Maximum Capacity
Step Down Voltage Transformer converts overseas 220/240 volts down to 110/120 volts. So you can use your USA/Canadian/Mexican items in a overseas country.
CE approved
Heavy-Duty continuous use transformer
Converts 220/240 Volts down to 110/120 Volts
One grounded outlet in front of unit (accepts 3 or 2 prong US and Euro plugs)
Hard wired with a European shucko plug also good for Asian outlets
Durable design with a heavy-Duty Cord

It does state Heavy-Duty continuous use transformer. So again I assume that is safe for the 480 watts that it will be handling.

Thanks for your help.

Yes continuous use rating means it is OK

Yes continuous use rating means it is OK

Thanks!

So illegal to sell into the UK given that it's suitable for plugging into a 13A socket, it must be supplied with a fitted 13A plug (and not a loose adapter)

Wrong. With the possible exception of S Korea Shucko outlets are not found in Asia. Areas of British influence, Malaysia, India etc use British outlets. Elsewhere 2 pin or sometimes 3 pin universal outlets are used. A Shucko will fit but the earth connection will not be made.
