Rotation meter colors

[Sdsparky569]

Can anyone explain the use of red white blue on rotation meters. Thanks.

More than likely:

L1 = Red
L2 = White or yellow
L3 = Blue or black

You should read the manual for your particular meter.

I have a feeling his question is why do they choose to use those colors - especially white?


Probably can't even claim made in the USA with many of them.

I am betting tradition.

I just remark them with tape.

I was hoping there was some historical story behind it.

Weren't those standard POCO colors for quite awhile?

They still are, at least around here. I run across line crews hooking up the HV in transformers with red, white and blue tape on them.

Red, white and blue are pretty easy to remember.

Seems like those are the colors used for navy shipboard 3 phase systems
