Thread: single and three phase

guys would appreciate a some advice.at work in the coffee bar there is an existing single phase coffee machine.it is fed locally from a small cu.a three phase supply has been run in next to the single from the main cu on the floor and a trial coffe machine has been installed.i have labelled the 415 as a precaution .is this good practice to have two machines on different supplies.cant find anything in the 17th

Can't really see a problem with that. Two machines, two circuits as long as the protection is okay no worries. Would be concerned if they tapped the single phase machine off one of the three phases of the other machine. Ur lucky u have machines. Its the old kettle and jar of nescafe for me.
