Amsterdam Electrical Device

Can one of you more international gents let me know what this device is? I think it is a generator transfer switch.

A USA associate is looking at properties and needs some advice as to electrical infrastructure.

Thanks,

HDP

Hoofd means head and Schakelaar means breaker. So you are looking at the main switch for this building. Looks like a TN-C grid and voltage is 400/230 V. 50 Hz, of course.

Thanks, Gunnar!
I knew your translation would be far superior to Google. Google gave me "emergency generator"!

Best to you,

...and I don't even speek Dutch! I use Swedish in the Netherlands. And they speak their whatever it is. And we get along quite well.

I'd use Google to find how to say "Thank You" in Swedish, but I fear what that translation might say!

Checked it. Seems OK.

On the left appears to be the incoming mainrising from below, with NH pattern fuselinks and CT's, then looping over to a 4-pole switch. I'm not convinced that this is a TN-C network - if this was the case then opening the switch would break the combined neutral/earth and would leave the system without an earth. My guess is that it is TN-S with a switched neutral.

Interpreting the literal 'head breaker', I suspect the translation would be 'main switch'.

 

[Skogsgurra]

Agree on Main Switch, I said so. I didn't see the breaker element in the blue neutral. Closer look shows that the N is opened when phases open. So it is a TN-S system. Definitely. Agree with Scotty.

Is there a standby generator on site?
Can you provide a better photo of the red nameplate?
No problem with main switch identification, but it may be part of a transfer switch, possibly a service main incorporated as part of a transfer switch.
If there is a generator there must be a transfer switch somewhere.

Thanks all. I have attached a better photo of the nameplate.

 

[Skogsgurra]

It says "Noodstroomaggregaat anwezig". That means that there is an emergency generator.
It also says "Eventueel uitschakelen" which, funny enough, means "Switch off potential" and then "met noodstop op aggregaat" which, of course, means "with emergency stop on generator"

So, you were right about the emergency generator. But that text wasn't possible to read from the first picture.

The generator was evidently removed by the previous tenant. Is it a reasonable assumption that there exists the functional equivalent of a service entrance rated transfer switch?

Thanks for all the help,

Dave
