That’s ok until you accidentally find you have an earth fault.
- Aloha 4y agoWell, in most cases I'm sitting on a chair isolated from earth, several feet in the air (wearing rubber soled shoes), so long as my test equipment shows 0v of potential to the chassis, its pretty safe. It could be that the earth bond has failed, but provided I have both pieces of gear sharing an earth, its all good.
- gumboza 4y agoFamous last words. Leave that scope probe ground clipped on something and every earth is floating live on your bench. Source: ex EE.
- Aloha 4y agoAnd at 110v, thats a risk I'm willing to take. I wanna note, I worked as an FSE for a telecom, I've been 'bit' more than once by 130v, and by 160v B+ in shit, the sparks from crossed neutral are fine. Anyone who is deeply concerned can buy an isolation transformer.
- gumboza 4y ago110v can fuck you up. Don’t take your own advice please. At least no one else should. Isolation transformer will only stop you getting killed one of three ways. Worth backing my experience up as well. Ex EE covering RF and power in defence sector. There is no room for arrogance or assumptions in dealing with safety.
