Anything is possible if you are creative enough. Who needs ISO/OSHA/DIN standards or safety precautions?

So, with the ground grounded?

Yes, and with the neutral connected to ground at the service entrance

Technically I believe it's ground and neutral are bonded at the "first point of disconnect"

If you have a disconnect switch outside after the meter that's the only point where ground and neutral are bonded together.

If you have no disconnect and the meter feeds directly to your main breaker panel ground and neutral are bonded in the main panel but not in any sub panels

Very helpful clarification, thank you.

You mean outside of the picture? Because it goes directly to the service without connecting on anything at your figure.

You should absolutely not connect the neutral to the ground in any part of your installation. The service provider does ground it somewhere, but you should not.

No, I mean where the white neutral wire connects to the main bonding jumper on the panel in the right side of the image.

I'm not sure where we are missing each other here. My reference is NEC in the US, are you in a different part of the world?

They are connected though. Maybe outside of your system, maybe inside of your system, but the point is neutral and ground are connected. Idea being if any metallic casing gets into contact with live wire your fuses break before you can touch the casing and get electrocuted.
