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
 
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.

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.
