hi coilers this is another of my project small DRSSTC I use a full-bridge 50B60 igbt I do not have OCD, PREDICTOR primary current over 300Ð when the arc may up to 400A in this coil did not explode none igbt very often strike in the primary winding constantly exploding capacitors in MMC this coil is so loud that the neighbors killing

Wow, awesome! You developed the single transistor tesla coil into a full bridge DRSSTC. How does it behave at higher pulse rate? Or hard arcing at earth?

it is quite normal for the coil but mains wiring in the house begins to melt
That's an interesting design. You seem to have a huge primary inductance of about 110uH. This way you can store a lot of energy in the primary tank until it is dumped into the secondary when it is pulled into tune. This sudden discharge probably causes a lot of voltage in the secondary, so that flashovers become likely. I guess you use long bursts (500us?) due to the slow current rampup.
Can you post a picture of your primary? Why do you have a toroid in the middle of the secondary?

Little DRSSTC from zilipoper ;D
primary current over 300Ð 
when the arc may up to 400A
