I’m looking to get the HPWC installed and want to check that the electrician is quoting the correct cable. Before I get a quote, can someone confirm what would be required to support a 15m run for a 3-phase 32Amp installation? (as per manual : 400V AC three-phase: L1, L2, L3, neutral and earth ground). From what I understand they’d use a cable that can support a higher amperage and a breaker that’s larger than required (ie 40Amp 3-pole)? Would this cabling be what they’d use? 4 CORE 25mm XLPE COPPER MAINS CABLE [XLPE4C25] - $24.20 : ElectricianSupplies, ElectricianSupplies Thanks, Shane.
