Hello Mr Rajaram Sir,
Are you going to Marathon race? Try to Stop your hurry sir. The QA is
about *UPS,
un-interrupted power supply unit* which provides AC current when main
electric power fails. Hence the question of earthing lead. Hello Physics
sir, where two pin top is provided, self earthing is there in the unit-
like mixer, grinder etc. I am least offended. Your lengthy responses,
whether refers to subject or not if there is matter I am retaining in
archive. What you feel silly need not be so to all others. I write on my
standard.I have admiration to you since you write on face your views. There
are members who only make ugly negative comments on my postings . They
degrade themselves. Personal vendetta has no place in groups.

KR Hello Gopalakrishnan sir
Your passenger train travels with lots of useless bogies. It
appears in one reply as answered by me. Yes I am also opening with
uninterrupted power supply plus other things with which you may not gossip
further. Earthing is used *to protect you from an electric shock*. It does
this by providing a path (a protective conductor) for a fault current to
flow to earth. It also causes the protective device (ei(the circuit-breaker
or fuse) to switch off the electric current to the circuit that has the
fault.
Nowadays almost all equipment used in the S & T (science and
technology) department includes electronic devices which operate on low
voltages. The low voltage equipment e g. UPS, Battery Charger, Inverter,
control systems, etc are provided with surge components like MOVRs,
avalanche diodes, gas discharge tubes etc. inside the equipment. The
internally used surge protection components prove to be inadequate towards
the surge protection solution. Hence to protect these devices from
transient over voltages produced due to lightning, switching of inductive
loads, ignition and interruption of electronic arcs etc., suitable surge
protection arrangement is required to be done at different levels. Hence in
all systems today, the facility circuit on internal boards of equipments
and out home boards where supply is received the measurements of :, {Fuses
• Fuses can be used to great effect in protecting equipment from over
currents. However, as they rely upon thin sections of wire melting, they
take a significant time to operate and the current passing through while
this occurs can still be sufficient to damage sensitive electronic parts. •
This has a major disadvantage of being usable only once, leaving lines
disconnected until the blown fuses are replaced. Circuit breakers Circuit
breakers are normally designed for power systems and though energy handling
capability can be increased to whatever level is considered necessary,
speed of response is of the order of 10 milli-seconds.} Those described are
added; today UPS is a waste. Even if there isa UPS and without earthing
plugged, for a short gap where ac main is not available, with the steady
flow ,discharge of ups can do without any earthing sir. The long answers
make one understand and to express hasty people like you, might feel
otherwise. And my physics is stronger where you are yet to confirm E=mc2
read with light waves. But it is unsafe but still might go for some time
where the potential difference is not so wild; the home will not burn
since the fuse will go off in milliseconds. That is why in the USA though
110 current still plugs are kept low; even if a child places the hand fuse
will blow saving the child; but we will not take the risk Pl understand and
do not raise 1954 questions. Till now by HIS GRACE I have not answered
anything 99.99% if I am not sure. You have to take care without being
biased. Pl do homework before releasing quora which are all gossip and old
ones. Majority of the people are well read sir. On the contrary, you forgot
to thank, I had appreciated one in the blue moon as you are so biased.
