they are under oil now, the humming noise is down a lot now except for the balast, also i have a 2 pole 20amp switch i am going to wire to the balast so i can switch it on or off and run it balasted on one pole of the switch or unbalasted off the other pole incase i want to use a differant external balast. This way i can shut off and bypass the internal balast with a flick of a switch then use it like that.

Alrighty , some more work done !
I got 2 of my 4 meters in from china the other 2 are stuck in a warehouse somewhere but i am assured that i will get them , lol ...
I installed a all in one power meter on the input of the ac power supply/variac and added a didgital volt meter to the output, just got to add my amp meter and my didgital thermometer and probe. !
Here is the video of the variac and the installed power monitering meters

I have run into a problem that only presented itself once the meters were installed in my 3kva variac, i had a so called utility outlet that i was using to power the heavy dutui equipment, and i saw a 20 volt drop at 20 amps !!!
Well first i checked the outlet by removing it and saw it had only 2 white wires that were 14-16 awg !!!!! Wtf and no ground at all !!! !!! Whaaaaaat ? Whoever wired this with all the same color white wire and sorely under sized guage wire for the breaker needs a punch to the head !!!
Soo i had to buy a single 30 amp utillity outlet and rewire the breaker box to the outlet using 10awg solid copper romex style black, white, ground.
So the breaker outlet is fixed but now but my extention cord is to thin and there is still a significant drop with 30feet of 14awg cord ! So now i got to buy 25 feet of 10awg cord and a 30amp male utility plug to make a new cord for my variac to prevent this voltage drop Aaaaahhh !
At least i fixed the breaker, it is properly wired and grounded now for 30 amps @ 120 volts.

Sorry I didn't take any pictures of the process I was kind of aggravated that what I saw and didn't think to pull up my camera but I did take an after picture of the new outlet when I get home I will add some pictures of inside the breaker
Edit... I may change it over to a larger spin lock Outlet and use it for powering only the variac which would have a very long 10 gauge cord with a male spinlock adapter depending on cost
Edit ... it appears this Outlet is only rated at 20 amps continuous so I will need a Nema L5 30 amp twist-lock outlet which I'm probably going to have to swap Breakers and simply add another receptacle besides this one and replace this breaker with a 15 or 20 amper
Ahhhhh , it's very easy to build a Mot power supply powering it sufficiently however is another story by the time I'm done I could run a pole Pig of the outlet required for this Supply !!!!!
