I have not had any problem with electric here lately.
I did build a new Light Bulb testing jig this week.
It is just a Lightbulb socket series wired into the hot side of a 2 Wire extension cord.
Works like a charm for testing, and before applying full power.
Nice Lightbulbs are getting harder to get. But the Socket will also let you use a Old School Fuse if you can find them. Or you can use a screw-in adapter to series a external Fuse, Lamp or load.
I can Post pictures. lol
Have Fun playing with electricity, and be safe doing it.
