neutral?

sundodger5 · 2019-04-04 10:02:47

Hi all, looking to add some smart switches to my home automation setup. Many of these require a neutral which based on research is not usually found at the switch location in Ireland. However when i opened up one of mine i see what looks like a neutral. See attached pic. Is that a neutral? Thanks.

I think this thread has run its course.

However I think it is important to understand:
1) Neutrals are not always blue.
2) Although neutrals should now be blue not so long ago they were supposed to be black.
3) Regardless what what colour a neutral must or should be some people ignore the rules!

To illustrate the risk of believing that all neutrals "must be blue" have a look at these examples:

Example 1 - Here the blue is the 3rd phase and neutral is black. Completely compliant with the rules at the time and still in use today.
Example 2
Example 3
