Re: UL Tesla Coil
Ted:
You should also note that the UL process, as you mentioned, cost around
$10,000. This is only for the testing, and it does not promise that your
product will pass testing. If it fails to pass test standards, then you
have to re-test, ie, another $10,000. You keep paying until you pass the
test with the product. The fee does not guarantee any product will be
granted UL approval in exchange for the fee.
