Does white wire have power?
White or gray wires indicate neutral charged wires. However, neutral wires may carry power and pose a danger of electrocution if not handled properly. White and gray wires carry power back to the service panel. Both hot and neutral wires have the potential to shock and injure you if not handled properly.
Does a neutral wire have power?

When a circuit, electrical component, or equipment is energized, a potential shock hazard is present. Black and red wires are usuallyenergized, and white wires are usually neutral. Metal electrical boxes should be grounded to prevent shocks.
Can you get shocked from a neutral wire?
The neutral wire does have current going through it. However, we do not get shocked when we touch something with current going through it, we get shocked when current goes through us. In this case all of the current that enters one end of the section of wire we are touching also leaves the other end.
