Connection of washing machine & dishwasher via a socket (T15)

Dear house-building friends

I have a question for you regarding an installation made in our house and hope an electrician among you can tell me if this could work:

We want to operate a washing machine (220V) and a dishwasher (220V) in parallel in the kitchen. My question concerns the power connection to an existing T15 socket (double 10A protected). Our plumber suggested connecting both devices via a common T15 plug: that is, device 1 is connected to L1, device 2 to L2, and both devices share the neutral conductor.

This way, no new socket would be needed, both devices would be individually protected since they run on separate L1 and L2 conductors; however, they would share the neutral conductor. Would that be a problem?

What do you think?

Thank you very much for your feedback and best regards,
Stephan

Hi,

I have little experience with electricity. However, I believe I know that what is supposed to be done here is not allowed.

Two devices on one plug, that is forbidden.

Get another professional opinion.

Thank you, I have come to accept that as well.

That is forbidden? I didn't know that. We have something similar and so far everything has worked. But I will also have an electrician come by.

As already correctly noted, 2 devices on 1 plug are not permitted Either install a 2nd socket (pay attention to phase sequence) or use a T15 double plug (the phases should be swapped there...) Or simply use a power strip. Both will then be on one outer conductor, but this should not be a problem considering simultaneity.

That is correct, and especially with electrical installations, the utmost caution should be exercised. These two devices simply do not belong to one socket. This can become a big problem.
