Electrical panel terminal blocks – proper connection, labeling and common faults

What is the role of terminal blocks?

Terminal blocks are the connection points between the panel and the external cables.

Common problems

• Loose connection.
• Burnt contact point.
• Incorrect labeling.
• Poor terminal crimping.

Inspection

We visually check for blackening, temperature and proper tightening. Each cable must have clear labeling so that it corresponds to the diagram.
