Random Thought Thread

A lot of people who get hit with 240v etc are only hit with 120 because it's usually only one of the legs. You'd have to get both legs at the same time to get 240.

Also, the amperage capacity of the circuit is usually irrelevant. You can touch a leg on a ten amp circuit or a 200 amp buss, if it's the same voltage, it's the same shock. It's issues that effect conductivity, not the amperage capacity of the circuit, that dictates the current.

"It's the amps that kill you" is looking at things wrong. You can touch the "1000 amps" of a car battery and not even feel it. But 1 amp of 1000v and you're toast.

Correct. You can't magically force a circuit to draw more current, unless you increase the voltage or decrease the resistance, so with those values fixed, the current capacity doesn't matter.

But it's the current that "does the work" so to speak. 10 billion volts can't do anything if current can't flow...it's called "potential" for a reason. In the case of the human body, doesn't take much current to be fatal (something like 0.1A), but we also have a pretty high resistance, so it takes a high potential to get that current to flow.

Having one of these in my toolbox has made me the resident commercial electrician at work. So if one day there are no 'likes' from me.....

Well I was going to offer a proxy for tomorrows sale but with the snow coming in almost 99% sure my work is going to be closed.

No fast interwebs at my house🤷🏼‍♂️

Same here, snow starting tonight into tomorrow, will be a slippery morning for sure. But…… being retired, I only need my coffee to start the day off. Snow removal can wait till later.
 
And they just emailed me. Closing at 1 today and all day tomorrow. Crazy how nobody can drive here in the city on little to no snow.

Growing up in the country we never closed anything. Now they close places before it even starts.

Oh well, since I am salaried I still get paid but I feel sorry for some of the employees that are hourly and won’t be getting paid.
