To ensure that electrical connections are properly tightened and secure, specialized torsion tools are necessary. Both overly tight and loose connections can be hazardous and lead to failure. Neither equipment manufacturers nor industry regulations recommend regular readjustment of connections. Even if a “hot” connection is identified during an infrared inspection, simply tightening the connection will not necessarily solve the issue.
The connection must be taken apart, cleaned, and reassembled with the right tool and torque. Additionally, replacing the end of the previously connected cable and making the connection with a new cable section is the safest option. A simple way to check if outlets are grounded is to use a socket tester. If the tester indicates an open ground outlet, it may mean that there is no means of grounding, or that there is a ground cable but it is not connected correctly. It could also be grounded to a metal electrical box, but the box is not properly grounded. It is important to inspect electrical connections regularly to ensure that they are secure and safe. If you suspect that a connection needs to be tightened or inspected, it is best to contact a professional electrician who can use specialized tools and techniques to guarantee that the connection is secure.
This will help prevent any potential hazards or failures.
