I think this forum should have a section just for electrical issues like this, separate from lighting in general and just focusing on stuff like Distro, electrical safety, etc... I know in some countries, electrical duties are part of the grips jobs, but for those of us in countries where these duties are part of the electrical department, it might be helpful to have a separate forum. Sorry for going off topic.

I've watched power crews do direct tie-ins on live circuits in emergencies. They wear around $2,000 worth of arc-flash protection gear and hi-tension gloves and NEVER do it by themselves, it's always a full line crew.

I had heard that California recently passed a law making tie-ins illegal, .......
It serves no purpose to post information such as this without a link to a credible reference.
Tricos are still made, a 5 wire tie in set in small medium or large can still be purchased. I will add that the design of some residential panels makes it difficult to attach a trico to the hot or supply bus. A tie-in using an appropriately sized breaker would be a better choice.
If you wish to obtain some protective equipment, insulating gloves and/or sleeves for class 0 work would be sufficient. In addition, you'll need to wear leather protetive gloves over the rubbers to keep from tearing or wearing through them. A pair of safety glasses will protect your eyes and absorb most of the ultra-violet light emitted during an arc-flash.

Electricity is dangerous. No doubt. But, it is knowable. It is work-withable. I imagine both Hal and JD have worked with it "old school" and got the job done and no one got killed.
