Combination Isolation Transformer,Variac and Dim Bulb Tester

[Ben Palmeri]

Hi,
Hope everyone is doing well.
Put this together over the last few rainy weekends. Previously, I had 3 separate units, and had to plug my Isolation transformer into the wall, then plug the Variac into the Isolation transformer etc…,etc.
Decided to put everything into one box. The toggle switch on the left selects one of the two available variac taps, The switch in the middle allows you to bypass the variac and connect the load directly to the secondary of the Iso. Xfmr. The Meter in the middle measures current ,voltage and power at the load. It cost about $13US shipped!! (The box cost more then the meter.)
The handle was left over from when I renovated my kitchen. I pays to not throw things away.
Cheers
Ben
