Totoalas,

Thanks. :-)

Can you put one 1KOhm 1% metal film resistor over the output and measure the DC voltage over the resistor.
(No other load than the resistor on the output.)

one 470 and one 560 ohms 5 watts in series   on the output  0.85v dc
without load  13.77 v dc    total r  1.030 kohms not metallic film

Totoalas,

I = V / R = 0,85 / 1030 = 82,5mA
P = V * I = 0,85 * 82,5mA = 70 mW.

OK, so you have approx. 70mW available from the mains neutral and outside ground.
Do you still have that output if you switch off all mains circuit breakers?

thanks gl for the power computation

no output when source extension socket is on   live amd neutral present
when extension socket is off  there is an output neutral present  live cut off
need to check next morming its evenimg  when
main cb off in he house 2pst live and neutral in a rcd breaker

Totoalas,

I'm not sure I did understand all of the above.
But, OK, I will wait until you can do the test.
Thanks for today testing. :-)

normal house extension socket    i swap the live and neutral connectiom to have the ac neutral the isolation switch and fuse for my experiment
in the plug i did the same the neutral was connected to the fuse instead of the live wire
only one wire neutral is connected in the plug   
so i can isolate theneutral anytime with protection at thesame timed
