Here is my final version of my DIY Breakout Box EU Receptacle - for AC Standby Power measurements.
My DCUU PM9913 this is a special power meter, this has in focus AC Standby power measurements, from few mW up to approximately 460 Watt.
My special Breakout Box, this is modified in a way, this accepts optional external connectivity with bench-top DMM.
Both AC Voltage and Current it can be verified due external DMM,s (two).
This is composed by branded and easy to be found parts. GE Industrial Solutions, enclosure. Legrand, Valena & Forix series wall plugs.
My NEON lamp this is used as 1mA current verification, along power-on indicator. :)
When my setup is ready and warmed-up, then NEON lamp this gets unplugged, and only the DUT this stays connected.
The On-Off switch, this is a small bridge for the AC current banana plugs.
a) I can safely switch DMM current input at 600mA or 10A, according my needs, with the load this staying on (by pass function).
b) I can protect 600mA input due over-current spikes when measuring pulsing PSU (by pass function).
c) I can use it even as regular On-Off switch
The entire design concept this is rather smart and simple.
Double AC outputs !!
All AC wiring this is made due 1.5mm wires, for the max of 450W load, such thick wires they appear as invisible factor regarding losses.
100% success, and I am 100% Satisfied !!! 8)
Now I have a super complete AC Low-power measuring setup too.
Additionally, my entire testing lab this is now 100% complete.

Professionally made work as always !! :)

Interesting use of, GE Industrial, Series SFK motor protection KIT. ;D = SFS05 enclosure.
Nice to see, this by-pass function implemented.
Blog readers they will find more clues, if they read this. https://www.ittsb.eu/forum/index.php?topic=1954.0 (https://www.ittsb.eu/forum/index.php?topic=1954.0)
I am glad to see this DCUU PM9913, with it Breakout Box, this now becoming a complete solution.
As far I know, DCUU mother company, this never involved to present their own Breakout Box.
Their own recommendation, its an optional pair of wires with crocodile clips. :P

Pair of wires with 4mm banana plug & crocodile clips, this is for testing of LED luminaries / lighting ... Only .
In the range of 2W ~ 100W.
I got scared by watching Chinese video footage, by DCUU workers, as product demonstration.
They were nervous, not paying attention at electrical safety.
DCUU PM9913 power meter, this supports permanent and quick-connect, wires connection.
I do prefer permanent connections, due my breakout Box, any electrical connections they are visible, this eliminates user mistakes, and increases safety. :)
Legrand, Valena wall plug, this is excellent for high loads, there is a tight fit, no matter of what you will connect to it.
Legrand Forix series, second best for smaller loads.
