Hello

I wouldn’t mind if I didn’t have a meter. With these old connections and colors you never know!

The Red is the guardian. is so common in older houses.

There you connect the green/yellow of Herd.

The blue is the zero conductor. The two belong together.

The black on black (2 times). The brown goes to the clamp of the gray.

For God’s sake… Such statements without testing and then from the old standard were also incorrect…. blue was formerly external conductor and gray neutral or zero conductor, according to your instructions you put 400V on a device for 230V with a high probability. This quickly gives total technical damage and fire hazard due to overvoltage

A tip:

Remove the lid from a normal outlet (preferably in the same room). There the same (old) colors are probably used.

If “red” is connected to the protective conductor contact there, then you at least have what the protective conductor is. Then probably “grey” will be the zero conductor.

The clamping block also suggests (position of the central screw!),

  • Left of the central screw are the 3 phases
  • Right of the central screw are then N + PE

That’s just a hint, better is, of course, retrospective.

Good luck!

Until about 1965 (plus a transitional period), the red vein was common as a protective conductor.

Don’t have to be.

Order a person skilled in the art, then there’s nothing “in the pants”.

ForHigh current connectionsPrevious:

  • L1blackorbrown
  • L2Red
  • L3blue
  • PE(PEN then)grey

__________

there only helps to view the cable in distribution ( fuses) where red and grey are placed

The following applies:

until 1966

pure protective conductor (PE): red

pure neutral conductor (N): grey

Zeroiter (PEN): grey

External ladder: black, blue, red (if not PE), grey (if not PEN/N)

Before 1965 other cable colours were:

  • Characteristics Black: external conductor, phase (L)
  • Characteristics Grey: neutral conductor, zero conductor (N)
  • Characteristics Red: protective earth (PE)
