You are asking the wrong question. You should ask " why is a Tesla coil
This is not an easy question to answer properly.
However, a small desktop coil would not require more than a connection to
the house electric ground at the wall outlet. In fact the NEC would require
this of a UL approved electric appliance. A homemade Tesla coil is not UL
approved, neither are some other physics demonstrations. Be aware of the
possibilities so you can handle them if they arise.
I have built several small coils that produce 5-6 " sparks and more. I
used a 7500 volt, 30 ma neon transformer. Don't let me discourage you. There
are plenty of Tesla coils in physics labs across the country.
