Coffee Machines

[MartyOne]

Hi all,
Is it permissable to supply an electrical appliance (coffee machine) that has two boilers and two main switches form 2 supply leads?? Not interconnected electrically, in any way total seperate control and supply?

The machine kW rating exceeds what is available from one lead.

This will be in a caravan and both supplies will be by seperate cables, not a permanent installation.

Appreciate any ideas, thoughts and facts.....

cheers,
Marty

Just to clarify.

This is one machine with 2 heating elements supplied by 2 different cables.

Do the cables have plugs?

What is the rating of each heating element?

Yes, one machine with 2 heating elements in 2 seperate boilers.
Yes, both cables have plugs
Each individual boiler is 2000watt

Sounds fine to me. But I wouldn’t plug them into the same socket.

It would be fine here in UK but as PP said best not in the same double socket.

The volt drop from here to OZ would have to be considered

Thought double sso were rated at 20A.
S.

One thing to consider is in the uk there should be one single point of isolation for a single machine. you will have to consider if this will be required or advisable in your circumstances.

Finally, if you are running from 2 different sockets into the same appliance, be aware they may be on different phases and therefore you could have 400v between lives if you were to open a cover. This should not be an issue if they are electrically separated but worth considering.

Not sure that’s correct. Take e7 heaters with 2 tarring feeds. 2 isolators for one appliance.

its possibley different for a simple water heater?
or do they class each heater as a different appliance even though they are suspended in the same water tank.

it would be for a machine that moves in most cases.
where there could be a danger of injury if it was isolated but unknown to the person working on it there was a second supply.

But I totally understand your point

Many commercial coffee machines have dual supplies. Drinks chillers in a certain high street bakers have two cords with two moulded 13A plugs.

The standard domestic circuit in Australia is 10 amps so the two plugs would have to plug into two different circuits, not 2 sockets on the same circuit.

Hi Marty
AS/NZS 3001 is the standard that applies here in addition to 3000. The standard for transportable installations.

you're from Aus so I assume the inlet is a 15amp flat pin or a 16amp 60309 ( ceeform).
You can upgrade to a 32 amp 60309 or a 32 amp 56 series but this can be a issue for event power though. My preference is 60309 as it's a superior standard

YES you can supply the van with 2 separate 15/16 amp supplies BUT they must be electrically separate ie with their own board and circuitbreakers. I prefer to use 16amp RCBO as a main switch.

I'm a kiwi electrical inspector I certify over 70 vans etc a year.
