In a main panel, touching the neutral bus is not hazardous if your grounding and bonding are correct. Ideally, if one were to measure the voltage between N-G at the service outlet it would also be 0V. If you suspect s ground neutral bonding anywhere other than the main panel itself, or a neutral ground reverse, you can use amp clamps around the metal gas and water lines to see if there's current (.2a is what they say can be lethal, and it can be hard to determine how much the system is actually taking since the water will absorb the current and act as a load. Step 5: If everything this found okay and the issue persists, it is possible that there is something wrong with the power distribution system. Atkinson Inspection Services for a complete home inspection in Orlando, Clermont, and the Villages. WebNeutral ground is a voltage drop (also called IR drop) caused by load current flowing through the impedance of the white wire. After the test is completed, the remaining fee varies based on your new wiring needs. If neutral wires are not connected to the ground then an electrical charge can pass through it. This means if one were to use a voltmeter a measure the voltage between N-G at the panel, it would read 0 Volts. I understand, but what would lead to any voltage being present? BillW. Still, if you can accidentally touch the neutral bus, you can accidentally touch the hot bus. In many cases, homeowners find out these scenarios as they plug in various appliances to their outlets.

The classical picture of atmospheric electricity is that the Earth as a whole is neutral, but that thunderstorms maintain a voltage of around +300kV at the electrosphere with respect to the Earths surface, with a current of around 1 kA slowly discharging around 500 kC of total charge separation. Also the white wire is your first to make and last to break, if you get hit, the neutral takes current back and you might only get some of it when you get hit to the ground , (where the neutrals and grounds meet at the main panel only) if there's current and you get between the hot and the ground, or between two neutral wired taking current back to the panel, you become the path and it is much worse than just getting shocked off of the hot wire while the connected neutrals are taking back most of the returning current, you can get hit harder off the whites as you can share a neutral between two circuits on different phases, and if there's no lights or anything taking up current as a load, you get it all, 220. as in example? Second, the type of answer I'm looking for is something like: "The difference in a properly installed should be below XX V because it is written so in regulation YY".
