Chassis Grounding

Support
1

Hi, not sure how to wire the chassis ground or if its required.

I’ve included an image (wiring|690x414) on how everything will be connected. Will a chassis wire/connector go from solenoid metal housing to metal holder for GX16 8 Pin then to a spare Pin say Pin 6 then from the Flange Pin 6 to the IEC Fuse Chassis Male Power Plug with Switch? Does the GX16 Flange need to be chassis grounded as well?

Thanks!

Hi Tom,

What’s the context? What components etc. are you using?

I see you’ve linked to some kind of file download site, but it’s not loading for me. Can you please just paste the image in the reply box, or use the upload button?

updated first post, the uploaded image shows the components thought it might be easier to list on image.

The only thing requiring a safety earth or ground would be the 230V mains. This has only 2 pins so power supply is double insulated and earth not required. The rest is low voltage.
The “Ground” referred to in the photo text is the negative side of the low voltage supply and yes it would need to be connected to get anything to work.
The low voltage supply would then be + positive volts, - negative volts or ground. Only a terminology issue.

Thank you, yeah just learning so my terminology isn’t up to par yet :smiley:

Just wasn’t sure if those metal housing and GX16 needed to be earthed because they are metal just in case somehow something gets shorted in the plastic case by touching it, but from what you wrote because its two pronged its double insulated and then because the three prong is connecting to mains its already earthed.

Hi Tom,

No worries, it’s always best to double-check with an electrician locally if you’re worried about it. Be sure to only work on power within the appropriate standards unless you’re licenced to do otherwise, but as Robert said, the potential for grounding issues shouldn’t be a problem on the low voltage side of your circuit, and yes, the terminology does get quite detailed in complex topics such as electronics modification. If you have any further questions please let us know and we’ll do our best to help you out!

yeah, I plan to get a electrician to look over it all but very hard to find someone who will look :frowning:

Hey Tom,

I’d check the white pages for your area. Should be plenty of electricians about.
