Home wire, can not use aluminum thread?,
Open line is absolutely ok! Dark or copper wire is recommended! You mentioned above, these appliances are very small power, four square aluminum enough, but the aluminum must pay attention to the connector must be connected, otherwise it will contact bad, causing accidents!
You use the aluminum core wire, I suggest you Ming Fu, plastic insulation wire laying in the air safe carrying capacity 34, rubber insulated wire in the air laying safe carrying capacity 32, each 4 corresponding to 1 kilowatts, so the aluminum core wire 4mm2 no problem.
No problem. 4mm2 is enough. The home line used to be 2.5mm2.
