3Phase wiring into single phase supply

Danger mouse · Mar 4, 2020

I'm looking to install a traditional coffee machine which has total power 3300w and the wiring supplied with it is brown L1, black L2, grey L3 & Neutal with earth.
How would this need to wired to operate on a single phase 16Amp supply?

Has the manufacturer supplied any installation instructions or wiring diagrams?

No wiring diagram other than the rating plate

Is it one that can be wired either 3 phase or single? Some you just link the l1 l2 and l3 but check the instructions

I'm guessing this could be the case, but if this was possible why would you ever wire this as a 3 phase

It’s an option that some do on larger loads, probably more for commercial kitchens

so I shouldn't have any issue connecting all L1-2-3 together in a single phase 16A commando plug

Without the instruction it's not possible to tell. Got a make and model?

If three phase machine, why would you put it on a s/phase?

The only supply available is 16amp single phase.
As the load is 3300w it should only pull just over 13Amps

You can't just connect and hope for the best. You need the machine instructions.

You will need the wiring diagram for different phase connections. If you do the single phase then the elements will be heated in series by the single phase meaning the machine will take a lot longer to heat than on each phase to one element. But contact the manufacturer they will certainly have the wiring diagrams and there should be indication and or jumpers at the connection point.
