Considering the efficiency of electric vs flame burning, electricity would usually more cost saving in the long run unless he is on max all the time which is doubtful.

Even I decided to go full induction in shop after cost comparison.

Its 50hz..

As previously you need the supplier to confirm but usually the machine should be adjusted to our Malaysia voltage to suit..

36kW 3phase would mean 12kW/phase thus 29Amps/phase well within the current carrying capacity of a 40Amp 16mm2 cable ..

Thus if your existing is already 60A 3pole(3phase) breaker there is no need to upgrade.. which will cost a bomb to pull in new larger sized cables and breakers/switchboards..

No..

For peace of mind, talk and get confirmation from the supplier..


Most of what follows are suggestions based on opinions rather than qualified advice.. So get in touch with the supplier directly since you are an interested buyer..

Edit. Logically running a motor on a higher voltage than its rated will overload as it runs faster, hotter premature its usage while having safety issues .. ditto for a heater element..

Picture showing the electrical switch with the red box highlighting a 3phase supply means that a 3phase is compulsory for the machine.. the timers are probably for an auto trans start probably for a bigger motor..

Thus most machines have built in tapping transformer adjustments or auto regulated to suit as many countries possible voltage/freq.. you have to ask them to do the adjustment(if necessary) before shipping it to you.

Buy new machine ask the seller make it accordingly to 415V 50Hz supply.
Not plug and play as it will blow a 13A plug top to bits.
Its a fixed installation device requiring a dedicated LNE circuit from DB box.

36kW 3 phase balanced load will give 64 Amps per phase.
The current carried per phase does not change whether you split the kW load per phase or you calculate the load as balanced 3 phase load.

You can check the calculations in this website if in doubt.

https://www.rapidtables.com/calc/electric/k...Calculator.html

Parameters are:

Current Type : AC - Three Phase
Power : 36 kW
Voltage Type : Line to line
Voltage : 380V
Power Factor : 0.85

Amps : 64 Amps

Cable size should be advised by the electrician, the cable conductors size, conductor type, insulation type, as well as the installation method dictates the current carrying capacity.

This is for factory use, not for commercial use.

Ok..

My mistake.. 36kw 3phase then doesn't equate to 12kw per phase..

Its a heater so purely resistive load pf=1.. say 415V nominal use your 380v..

Cable sized for 64amps so use 3x25mm2 + 25mm2 full size NE..
Probably better use 35mm just to be safe..

Agree?

Not plug in but as a fixed connection installation..

So find a smaller snack frying machine as this machine will cost you to have a 3ph 100Amp switchboard for your shop..

You were right that 36kW on 3 phase means 12 kW per phase for all 3 phases, because its a balanced 3 phase load. But calculating from 3 phase or 1 phase load should get the same current in Amps.
Also right on resistive = pf of 1 for the machine. Used p.f. = 0.85 because I'm too used to using a standard p.f.

Cables will depend on his circuit breaker size, but he will need 5 wires, 3 phase + 1 neutral and 1 earth.

Fixed connection is pretty much the way to go for these machines, best to have an isolator installed close to the machine though.
