Great video color codes for different countries. I live in the USA and I had to do some work that had to b shipped to China and mexico the color codes for different countries really helped thanks💪
In the USA, if there is a 120/240V 3ø 4W delta system, one phase will have a higher voltage relative to neutral, at 208V (or 415V in the case of the extremely rare 240/480V 3ø 4W delta) and this is the high leg and is required to be colored orange per article 110.15 of the national electrical code and is required to terminate to the center lug, or phase B in panelboards, switchboards and switchgear. In metering equipment the high leg will be on the right hand side, or phase C. In a disconnect, aka safety switch the high leg is allowed to terminate to phase A, B or C also good practice is to keep everything in the building consistent. In most cases high leg delta systems are seen in older commercial and industrial facilities and rarely seen in new installations, but since there are many legacy systems remaining across the country, it's very important to have a solid understanding of this to avoid dangerous mistakes. Hooking up a single pole breaker to the high leg for line to neutral loads will result in smoking equipment when the breaker is turned on.
Different than in the video suggested: According to IEC 60445:2021 to following colours are used in DC systems: 6.2.4 Line conductor in DC system Line conductors in DC systems shall be identified by the colour: - RED for the positive line conductor, - WHITE for the negative line conductor.
So my ceiling light box has lilac, green, and grey/white cables connected to 3-rail-screw terminal It's labeled (in same order) as N, GROUND, L Should I be worried? (House is probably from 60-90's period)
I wonder about Saudi Arabia they have 127 volts what is there color code and is 14 gage wire used on 15 amps and 12 gage wir we used on 20 amps do they use American standards boxes or British standard boxes and there outlets British standard for mounting and terminal connections with American standard plug on the front
comunist colors (yellow,green,red) used in China were used also in USSR, green it's very dangerous for young electricians, probably they are instructed about old one too

Hello Antonio, thanks a lot for your positive feedback!!!

Thank you! Learning something new for me.

BS7671 *IS* the IEC standard.

At 8:11, why neutral is blue ?
Hi
I am electrical technician.and your electrical technician
I have cord on a wet vac the wires are green/ black/light green
I put green on ground and the other two on the other past - don't work help
Then there’s also pink, purple, and (I think) cyan for 600v. Above that voltage, all phases are black
I wonder about Saudi Arabia they have 127 volts what is there color code and is 14 gage wire used on 15 amps and 12 gage wir we used on 20 amps do they use American standards boxes or British standard boxes and there outlets British standard for mounting and terminal connections with American standard plug on the front
What are the settings for Battery if experience low voltage on display
Useful information, thank you
It's a pleasure to help!
IN ONE SLIDE WHERE IT SHOULD BE LABELED 277 IT IS LABELED 227
what colors are used in thailand
Copper wire what match red or black?
Robert looks like a million volts went through him
🤣🤣🤣🤣🤣⚡⚡⚡⚡
Great information thank you
Thanks a lot for your comment!
