That wire looks a little funky, what is going on there?
Looks like the insulation is damaged. Twisted.

Ya it’s a little twisted but there’s no exposed wires. That’s the wires coming off of the driver.

Someone mentioned grounding?
I grounded both AC and DC sides.
I’m in the US, not familiar with EU stuff.
If you are getting a shock from the driver chassis, your body is completing the ground.

Im not sure what I need to ground it too. Should I mount it to the wall. Would a wire rack work or am I turning the rack into a giant shock shelf. I guess I haven’t noticed this in the last year or so. I just had driver sitting on top of tents. Or in my shed I had it mounted to a piece off wood.
Thanks for the help! I just wanna make sure it’s safe!

It should be grounded to your homes ground… if you’re getting a tingle it’s either not connected (loose cable) or you have a current potential between yourself in the ground, ie, you are connected somehow to the live connection. Like if say, something bridges inside the case… you don’t happen to have a multimeter do you? If it’s scenario A, we’ll just ground it. Scenario B RMA it, that’s a defect.
Hopefully that made some sense? I confused myself a bit to be honest. Don’t put it on a wire rack, then you’ll get a tingle off the whole rack! You could attach a wire to the case and then plug the other end into your ground system but… meh.

And that sounds super fucky, should work no problem. Did you wait long enough after turning it off? I don’t know if the Meanwells have some sort of rapid cycle protection.

Ya I’m confused somewhat also. Three wires from plug to driver. One marked L,N, and this weird symbol. L was hot, N was negative and the symbol ground.
Thought the ground would go through the outlet. I’ve wired outlets before. I know there’s a ground wire or should be that’s my confusion.
I had my other driver on my rack and rubbed the inside of my tricep on it. I knew I felt a tingle. I put a piece of cardboard under the driver.
I did email the company I bought it from. They say ground wire. They also said they can’t help troubleshoot DIY builds. Warranty ran out a month ago lol.
Thanks for taking the time!

Even when the lights off with the smart plug there was still a tingle. I’m stumped!
Thanks for taking the time to help!

You have a problem with your ground in the room, if not the house sounds like. If you have one of the outlet testers you can test that for piece of mind. Or something weird. Out of my depth too lol.

WTF is a house ring main
1 Like
Ring mains are a string of outlets, covering for instance a room. One breaker. Then the house ring connects all of those… so wires.
I’m not aware of the term being used in North America.

Its a UK term for what Chemical described here in Canada, and why so much cable gets used, here each room has a ring. In the UK you would have just one for each house floor level, not room.

I decided to keep the wattage unchanged. 300W . now once the pwm adapters get in, I’ll be able to remotely control the dimming.it’s not the pretties but it’ll earn a golden apple.
All hail the goddess etc etc.

That sounds exactly like a floating ground.
Grab a multi-meter and check AC (& maybe DC) voltages between the metal case of the driver and house wiring ground. I’ll bet you find something.

Are you talking about a wire to a potentiometer to dim it “remotely” or do you have a 10V PWM dimmer you can control over wifi?

I gonna read up on using a multi- meter and watch some YouTube videos. I bought one when Sears was giving me free money monthly after we bought a mattress. Glad I did!
Here’s response from Meanwell. They don’t seem concerned.

I have a supergreenlab control board. it controls things via 3pin molex conectors has wifi etc etc. but it only controlls (timer/intesity/up-down ramping) their led board. I was a beta tester for the meanwell connector/adapter. they have just announced more connectors and I’ve been pestering the guys to sell me a couple more.

Looks like Gary was being ‘careful’ with what he said.
I’d look at running a separate ground wire from the driver’s chassis to a solid electrical ground if you cannot isolate the issue.
This step-up Xformer you are running, does the electrical ground (from the wall) pass through to the driver?
I’ve seen cases of floating grounds on switch mode supplies hitting 60 to +100VAC (but very little current). It can be a safety concern.
