Ferrites, and buzzing
Hoping to start a discussion, not solve any issue here. I have a "watt's up" wattmeter clone from Windy Nation. This came with 8awg leads instead of the usual 12awg. I'd found its AH and KWH fi...

I smoked a 9.5Kw 3-phase transformer by an overdose of wishful thinking. Shorted all three X secondary windings before the 10-amp breaker tripped. So much for my SCR PWM control circuit.
Put unit to work
Have caps ready to clip
Resist connecting electrolytics in reverse polarity.
Pluck your magic twanger by passing the ferrite near the wire.
If it starts to scream - try cap #2
And so on.
If you want to buffer lower freak ripple a 470uf electrolytic will help
RCL can be soooooo much fun! Resistance/ Capacitance/Inductance
