Color coded terminals ??

[elgato]

I saw something today that is new to me. There was different colored ink on many of the terminals in this distribution box. This was a townhouse built in the mid-80's. Was this some type of installation aid for the construction electrician??

It looks like someone took some colored sharpies to the terminal screws. I don't know why.

Would the electrician's in your area have been conscientious enough to have torqued them to a specific tightness and then marked them to that effect?

May each color represents the use.

Blue - bathrooms, pool, spa (although they aren't GFCIs)

Green - family room, living room

red - kitchen or security

yellow - bedrooms
