Thanks Paul, mostly I don't deal with line voltages. And when I do I like to hook things up cold, stand back, switch it on, and be ready to switch it off if it goes pop and starts to sizzle.

Hmm, I should look into a GFI. I assume I can get one that I can plug into the outlet and then plug my distribution strip into that.

This one uses split bobbin construction with large creepage distance. It's rated for 4000 VAC isolation. I got one a while ago, and I've measured the capacitance, primary to secondary, and it's 33 pF. The price from Mouser is about $27 for one.

You can mount a standard GCFI in a plastic or metal outlet box, along with a power cord. That way you can move it around the workbench or shop to where you need it.
