morning bunch of trouble makers, hope everybody is happy and well.

I build classA amps, pres, and phono pres, never seen one with positive ground. I buy a switch that will handle the amperage, or use a trip circuit so switch never sees the load. Bubba

Check out the circuits switched by transistors.

I too size my switches and SSR's appropriately and always switch the hot. The downside of switching the ground, is that you can become the ground poking around inside the cabinet.

Morning OFC. Happy Shatterday. Nice cool down today. Trying to wake up....feel like I have been driver. Probably self inflicted. Don't remember much about last night.
Gonna go out to the veggie garden and clear my head.

Right! I try to follow the rule of keeping one hand in your pocket while poking around, but sometimes, I might forget and need the help, getting confused about positive or negative ground adds to the mix. some of the vacuum tube amps I build have had rails as high as 610 volts.
Not the highest, but plenty enough to get your attention.

Yep, nothing like doing the 60 cycle shuffle to get your attention.

Just don't want to complete that circuit through the chest. I guess that would be "reaching ground (be it positive or negative) potential"......is a bad thing.

I had a 7KV DC shock when I was 17 and working in a government lab. I was lucky to get away with it. I was thrown across the room and came to on the floor with people standing around me. I had burns on both hands and my face. I was looking through a window of a vaccuum electron beam furnace when a molten iron bubble blew and shorted the power supply to the metal bell jar.

Afternoon ya O'l farts. Been working on the yard and veggie garden since 9 now 2. Great productive outside day. Everything is as good as I can make it. Feels good but I am pooped. Think I will suck down a beer, take a Jacuzzi and go out to dinner.

 

[Hippie420]

Worst I ever took was the neutral side of 220 3 phase, 30 amp. Accidently touched it with my right hand while my left arm was resting on a 4" copper water pipe. Blew me off of the top of a Baker scaffold and into a water puddle on the concrete floor.
I come to and try to get up and the morons kept pushing me back down and telling me they had a meat wagon on the way.
I finally fought 'em off enough to sit up, but when I tried to talk, all that came out was jibberish as my tongue felt a foot thick. Got my speech back and told them to cancel the ambulance. After arguing the point for a few minutes, they complied. Dusted my brains off and went back to work. General contractor said he wished he had a hundred of me.

Ahh come on I remember you telling me the story how you dropped the toaster in the bath with you to see the pretty lights .

Damn GFCIs took all the fun out of it.

Ever get hit with 277, 20 amp? Feels like someone wound up a steel rubber band and let it fly. Acutally burns a black spot on yer hide, too.

My worst was 120 volt in a grounded lift soaking wet from a wet saw cutting through a wall for a dust recovery system. Went to tie in the controls and got rocked.!!
Got hot with 277 one time as well working on a 480 volt well pump, that ******* sucks too.

I was doing a Sparky stint in the 80s to feed my family We had just came back from a cruise around lunch and were all crawling back up our ladders when I and few others got tapped hard. Found out that a sheetrock crew had flipped a breaker we forgot to lockout . Yeah, we were higher than sheitt.

Airbone, 120v kills more peeps every year than the higher voltages .. 120v constricts your palm and finger muscles around the volt source, not allowing you to remove yourself from the current, .. people die . Higher voltages with the higher amps will kill but usually just blows a chunk out of you as your flying 10 ft away.
