I’m doing research on some electrical standards in your country. In particular about the usual amount of phases, their Amps, Voltage, and presence/absence of a 0-wire.
How are these things usually done in Portuguese homes & businesses?
For instance, in my country most homes use 1 phase(35A) but many are switching to 3 phase(25A). Businesses often have 3x50A.
Thanks in advance!
