HVAC cable grounding systems and methods

A communication cable for a heating, ventilation, and/or air conditioning (HVAC) system, comprising:

• a plurality of conductors extending between a first connector at a first end of the communication cable and a second connector at a second end of the communication cable;
• and
• a cable shield surrounding the plurality of conductors;
• a first shield connector external to the first connector at the first end of the communication cable and a second shield connector external to the second connector at the second end of the communication cable, wherein the first shield connector, the second shield connector, or both are configured to electrically couple and mechanically engage with an additional shield connector of an additional communication cable,
• wherein the first connector is configured to couple to a first controller of the HVAC system, the second connector is configured to couple to a second controller of the HVAC system, the cable shield is configured to electrically couple to a single electrical ground point electrically isolated from the first controller and the second controller via one or both of the first and second shield connectors to dissipate electromagnetic interference through the single electrical ground point, and the first shield connector and the second shield connector each extend outwardly from the communication cable via a respective flexible shield extension.
