Non-invasive wire testing device

A non-invasive wire testing device for testing current in a wire, comprising:

• a body having:
• a handle portion for gripping by a user;
• a distal jaw fixed on the handle portion, the distal jaw including a U-shaped ferrite;
• a pivot jaw rotatably coupled to the handle portion, the pivot jaw including a ferrite block for selectively contacting the fixed jaw to enclose a channel, for receiving an wire on an axis within the channel when the pivot jaw and the fixed jaw are in a closed position;
• and
• a Hall effect sensor coupled to the distal jaw,
• wherein in the closed position, the ferrite block is configured to move against the U-shaped ferrite to form a magnetic loop around the wire, and the magnetic loop magnifies a magnetic field generated from current flowing through the wire to the Hall effect sensor for generating a signal indicative of the current.

A device for non-invasively measuring current within a wire, the device comprising:

• a body having:
• a handle portion for gripping by a user, the handle portion including a power button and LEDs disposed thereon;
• and
• a distal fixed jaw extending from the handle portion and having a U-shaped ferrite defining a channel;
• a trigger assembly rotatably coupled to the handle portion, the trigger assembly comprising:
• a distal pivot jaw opposing the fixed jaw;
• a trigger extending from the distal pivot jaw;
• a ferrite block slidably mounted on the pivot jaw;
• and
• a pivot jaw lock;
• a Hall effect sensor coupled to one of the fixed jaw and the trigger assembly;
• and
• circuitry operatively connected to the Hall effect sensor for selective activation;
• wherein:
• in an open position, rotating the pivot jaw lock into an unlocked position releases the trigger, biasing the pivot jaw away from the fixed jaw for receiving the wire;
• and
• in a closed position, the user:
• positions the wire within the channel,
• presses the trigger biasing the pivot jaw toward the fixed jaw to contact the ferrite block with the U-shaped ferrite, forming a magnetic loop surrounding the wire,
• and
• receives an output from the LEDs indicative of the signal communicated by the circuitry from the Hall effect sensor.
