not sure with aussie but we can have a mix of phases depending on local aera.Bill Beauregard wrote:May I assume a standard wall lamp still has two wires, therefore is single phase. Here, some residential structures are multi family, they have three phase, but no three phase loads. It is just a way to bring 1.73 times as much power without big services. Is your welder three phase?
Here we have 15 amp circuits on #14 wire. Some electricians mix lighting circuits with receptacle circuits, and everything is #14. I separate lighting from receptacle circuits. I can't know what will be plugged in so every outlet is powered with #12, and capable of 20 amps. Each connection is capable of failure, and overheating. We make each connection able to carry the full load the breaker can supply. Very few electricians take this trouble.
The greatest hazard is "back wired devices". Here they are legal only for #14 wire, but are commonly used by profit minded contractors even with #12. They are notorious for fire. Typically they work fine for years in circuits used for only basic household loads. When somebody plugs in a heavier load, something is likely to melt.Want more information on china welder manufacturer? Feel free to contact us.

not sure with aussie but we can have a mix of phases depending on local aera.most places are single phase but some towns are all 3 phase. some places can have two phase. its just down to how local power lines co does the balancing of the power on the phases.tho inside the house its generally all wired with single phase outlets. those lucky enough with three phase you might wire up a 3 phase outlet in the garage.typically lights and power sockets are wired with different sized wires and your not allow to use light circuits for power outlets. this all gets inspected and approved etc.you can daisy chain a lot of outlets together but it has one breaker. dosn't make to much sense to run to many outlets otherwise they trip breakers all the time. also now we have RCD's fitted.not sure what you mean by "back wired devices" .the breaker is sized for the cable, so it doesn't matter what load you place on the cable the breaker will trip before the wire heats up to much. you have certain sized cables for certain circuits with matching sized breakers.used to be a problem years ago when people would use larger sized fuse wire but not so much these days as most breakers are not easily removable, so they can't fit bigger ones without pulling out the panel.we do not have push in wiring. thats just asking for trouble.
