Hi folks:

I am in agreement with at least the vast majority of the content of
Garth's post, and he is 100% correct in stating that 13 of the
European devices, if installed int he same household/office building
(and if each was installed on lines belonging to the same leg of the
utility vendor's supply transformer, which is external to the
home/office) if they each contain only one capacitor of 15 uf each,
would total almost 200 uf total capacitance, and that 14 would total
around 210 uf capacitance. In other words, much as Garth has
reported, when capacitors are placed in parallel the total
capacitance is equal to the sum of the capacitance of each capacitor
in the circuit. And, as Garth has pointed out, the total inductance
-- and therefore the total incductive reactance -- offered by the
wiring in the home or office would be insignificant at a frequency of
50 Hz or 60 Hz, and thus would not tend to act to counteract any
excessive capacitive load across the line.

BTW, I have stated in the past that I disagree with some statements
made on the list group by Shivani, and this matter is one of the
points on which I disagree with her.

with care,
