What aids in achieving a good electrical bond in meter pan bonding connectors?

A good electrical bond in meter pan bonding connectors is best achieved using small, sharply pointed bolts. These bolts are designed to penetrate surface contaminants, such as paint or corrosion, which can compromise the conductivity of the electrical connection. By using small, pointed bolts, installers can ensure a more effective mechanical connection with better electrical contact.

The pointed design enhances the ability to create a secure and solid bond by allowing the bolt to dig into the surfaces of the materials being joined. This is critical in maintaining a reliable electrical connection, which is essential for safety and performance in electrical systems.

Other options do not serve this specific purpose effectively. Heavy-duty adhesives do not provide a mechanical bond necessary for electrical connections, and while long threaded bolts may improve the mechanical connection in certain applications, they may not penetrate surfaces as effectively as sharper bolts. Insulated wire connectors are meant for joining wires together and do not facilitate direct bonding to the meter pan itself. Thus, the use of small, sharply pointed bolts remains the optimal choice for achieving a good electrical bond in bonding connectors.
