a few extra $$ for a small water heater could go a long way.

Different countries observe different standards. Different uses have different colors. I don't see the standards converging any time soon.MicroSMD Lab wrote:Gladiator wrote:Just for the sake of the original discussion...

AFAIK white is almost always neutral. The switch on the fame switches the temperature. The blue lead is also switched via the diaphragm. Since the temperature may be adjusted while the unit is already in use I would prefer to use the neutral on the white wire.

True, I have seen this with a couple of devices but 220v seems to be 2 x 110v for the most part, I'm just trying to lend a helping hand hopefully without misleading or confusing readers who may not be "electrically inclined".adnj wrote:Trinidad imports electrical components from all over the world.

The picture you posted previously shows the coil resistance being switched via the white wire not the blue. I agree that the live wire should be switched but in this case both live and neutral are switched via the diaphragm. However, the white wire switches the coil resistance, which, will very likely be switched while the unit is energized (external switch on) right? Now while switching, if we use the white wire as live, momentarily we would have a loose live wire very close to a possibly wet hand, the ground goes to the water chamber, not above the diaphragm so guess where the live wire will be going to complete the circuit and which company will be getting a bad reputation!
I am an engineer, but not electrical. I guess Prof. Julien and Mr. Lutchman went way beyond 2nd year EE with us....

This is true but since the white wire switches the coil resistance if we use the blue wire as the live once the diaphragm makes contract then even if the coil resistance is disconnected via the switch then one leg of the coil will always remain energized which will be another hazard in itself. I prefer the live to go to the switch contacts as how all appliances are wired

When looking at a 3x1.5mm^2 Rhino cable (locally manufactured?) yesterday, I noticed that the colors are brown, blue and green/yellow.
