Sorry, if this is a duplicate question...

[potofu]

I'm not familiar with notation of electrical system and I saw this:
AC208V 3P 3W+G E3

I understand 'AC208V', '3P', 3W+G'. what is 'E3'?
Does anyone know?
Thanks.

Where did you see it (on a cable, a panel, a transformer, something else)?

 

[potofu]

err... on the CAD drawing of a equipment with step up transformer init.

Could be electrical sheet number three of the plans.

Or it could refer to a note or to an item on the electrical equipment list.

With the new NECA guidelines out, the specifier has to enumerate the number of electricians it will take to install the item, E3 means it will take 3 electricians to install this transformer.



Only kidding :lol:

It does look like it may refer to the prints - E3 - electrical page 3
