[QUOTE="Devnet, post: 530820, member: 35317"] Hi, I’m trying to buy/install a large commercial boiler which is 3 phase and I’m trying to understand the supply requirement to see if my existing 3 phase supply can run it. The unit requires approximately 70amps but what I’m getting mixed feedback on is if it’s 70amps per phase required or if that 70amps is split across the 3 phases so 23 odd amps per phase. Details of the specifications from manufacturers are below any advice appreciated. Supply Voltage 380-400 Frequency 50-60 Kw 48 Power Cable 5 x 35mm2 [/QUOTE]
