Electrical grounding and bonding is sometimes overlooked yet remains an important facet of installing an electronic message center (EMC). The Dealer/Installer as well as the EMC owner have much to gain and value from adhering to best practices to ensure a safe and functional sign system. Check out this video and information below to learn more about how to properly ground and bond an EMC.
Proper electrical grounding and bonding is not just for safety.
Reducing Ohm resistance will contribute to a well performing EMC.
Here are several suggestions to consider:
Proper grounding is a commitment to safety and guards against electrical harm. Grounding provides a direct path for electrical surges or lightning strikes to dissipate harmlessly into the Earth, safeguarding both our customers and the public. By prioritizing this vital safety measure, we value the well-being of every individual and strive to create environments where everyone can feel secure.
Protect the Sign
Grounding and bonding also minimizes electrical resistance within the circuitry. By reducing resistance, our signs operate more efficiently, requiring less voltage to power through loads or amperage. This optimization not only prevents power-related failures but also prolongs the lifespan of our signs, ensuring reliable performance over time.
Dedicated Circuit: Ensure one dedicated circuit per sign, though it's recommended to have one per face.
Grounding Rod: Install a completely buried, in-earth 1/2" diameter ground rod, minimum 6 feet long.
Copper Wire: Use continuous 6 AWG copper wire without any splices or joints.
Ohms Law & Why Resistance Matters
Ohm's Law is a formula used to calculate the relationship between voltage, current, and resistance in an electrical circuit. It's an important factor because with a high level of resistance, a circuit will require more voltage to deliver the power demanded by the EMC. In other words, the feed will struggle to meet the demand.
Specific instructions for electrical and grounding can be found on pages 6 & 7 of our Installation Guide.
Proper installation based on these guidelines will make the sign system safe, and contribute to the optimal performance of of the EMC.
