Need help. 3 phase system. Neutral line arced and melted
upon connection of connector with 3 phase power. Why would
that happen?

Answer Posted / pinky

I have a connector that connects to a piece of equipment.
The connector has many pins mostly for monitoring signals
coming from the equipment and for supplying 3 phase to the
eqpt. When I connected the connector to the equipment it
blew up. The neutral line melted into the piece of
equipment. Why did the neutral line blow.
