ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Un-harmonized color code -- Not too serious!

Gray is acceptable as a neutral in the NEC though, this would give North American electricians an unfair advantage.

With regard for the DIY darwin mob also..I propose bare for phase and neutral,(separate PVC conduits obviously) but due to the use of bare for ground/earth in many places, it can't be used in the confusing standard, therefore I propose clear insulated grounding wires with bare phase and neutral...

and 3 phase?.. too simple, all commercial/industrial supplies will now be DC only...
