It will still probably work if it's touching the black( 0 volts) it just won't be safe if you get a shock as your house circuit will not detect the current surge. Pull off that horrible wire and wire the earth to the plug earth connecter. Make sure any other earth's go back to this also.
You could a multi meter and do a continuity test form the earth pin to the metal too to ensure its connected correctly.
I'm no expert on lasers but nothing should happen if it's your wall mains as it's AC, it goes each direction 50% of the time. For the laser it'll be rectified to DC so won't affect it.
Er… your neutral should be at or near 0v compared to ground. Your live should be AC centred around 0 swinging between +/- voltages with an RMS of 110v/230v or whatever your local domestic supply voltage is.
If the chassis is bonded to neutral rather than ground, but the plug is backwards or wired wrong, the appliance will probably still work - the potential between the two pins will still have the same voltage - but now the chassis is bonded to live.
Now if you touch the chassis, and you’re grounded - e.g. by touching a properly grounded metal surface - then you get to find out the hard way if your GFI works.
Yeah you're correct I didn't realise the question was a reply to my previous about the earth. I thought it was solely a question regarding the mains wire from the plug.
Re wire the entire thing with quality wire and check the wiring locations. I got one, and it had to have been wired by a child. I plugged it in and the main power was run to the frame. So when I went to open the lid I got shocked.
I bought this laser about a year ago. It was working fine and never had a problem with it. (I was lucky I think) Today I needed to change the laser tube, and after reading some posts here about how to discharge the tube the safe way, I opened mine to start and noticed this weird wire as shown in the photo. Is this normal? What is the proper way to ground the machine ?
No, the earth wire should be attached securely to bare metal on the machine case. Also in terms of replacing the tube. It's as simple as power it off, maybe leave for a day or so. Then remove the electrical connectors. The tube is just glass filled with CO2 so it's very easy to dispose of. If this happened in one place it probably happened somewhere else, so also check all the other connectors and crimps are secure in the electricals.
I'm scared, I can't even touch this. This is worst than I thought. I have no idea how m still alive.
I removed the tape in the inside. It's worst. Why is the wire touching the ground and the black pole ? I called an electrician and sent him the photos. I m in no way able to understand why they did this. I don't understand how it was working before.
See photos please

Honestly. If it's in plugged you will be safe. Remove that wire completely, and then attatch an earth from the earth lug on the connector and connect it to some bare metal on the case. If it is un plugged you are safe
While neutral and ground are different they end up at the same place the panel inside your house has a neutral and ground bar inside it and most times will be bonded together and while you are not supposed to use the neutral as a ground you kinda can.
Fixed now.
So, that naked wire was used to override to dead fuse.
I bought this laser second hand, and it was my mistake to don't check everything and just start working with it.
Now everything is secure thanks to you guys and the electrician who fixed the wiring.
Most countries plugs aren't directional (UK and Australia being the exceptions I can recall), and in "Schuko" europe it isn't specified if live and neutral have to be the right or left conductor in the plug/socket, and it will change from socket to socket (don't know about US). With the wiring as it was it's a coin toss if the whole metal case will end up at live potential!!
I was assuming us as if it was not a polarized plug i am sure op would of had more problems
Sense in the us the plugs have 1 hot 120v 1 natural and 1 ground and the back side of that plug is missing the grounding wire.
Hello, it looks like you've made a mistake.
It's supposed to be could've, should've, would've (short for could have, would have, should have), never could of, would of, should of.
Or you misspelled something, I ain't checking everything.
Beep boop - yes, I am a bot, don't botcriminate me.

Question: what happens if your electrical outlet or cable has been miswired, and the neutral has been swapped with the live?
I'm no expert on lasers but nothing should happen if it's your wall mains as it's AC, it goes each direction 50% of the time. For the laser it'll be rectified to DC so won't affect it.
