I agree
The color code has always been problematic.?
?
This one happen to me.
Everyone knows green ground and black is hot. But at one time in electronics black was ground and green was high voltage. The electronics industry change this color code a long time ago
?
I got at auction a 3 phase cord wire by a old person in electronics. It was easy fix.?
?
I think most world uses yellow/green wire for ground but chart some do not.?
?
In America at one time gray could for any thing. Now the gray is the neutral for 480 volt today.??
?
I always think home voltage in the UK and about have world home voltage 220 volts in the children bedroom.?
From what I understand that 220 to ground. 2 wires off pole. { Back 1920s LA used 220 volt 50 Hz or 120 volt 50 Hz from the stories I been told. }
?
We use 120 to ground and 3 wires off the pole.
?
Slowly most countries are switching to 110 or 120 volt for home uses and only a stove and or big ac use 220/240 volts.?

开云体育Note that color codes have changed over the years, so you have to match the color chart with the year your building was wired.? I hear the UK really swapped colors around.Always check with a meter, I've seen yellow/green used for a live wire.? I wasn't expecting that, I had to knock through the plaster to a junction box to fix it. On 09-Feb-25 8:30, davesmith1800 wrote:

开云体育With our reducing magnetic field, we don't need as large a solar event to cause the same problem as the Carrington Event you referred to. So, expect problems.On 05-Feb-25 1:20, davesmith1800 wrote:
