Service Entrance Conductors vs. Feeder Cables

In multi-unit buildings, HEP differentiates between service entrance conductors that terminate at a main disconnect and feeder cables that distribute power to sub-panels, applying distinct grounding methodologies for each.

Panelboard Bus Bar Material

Aluminum bus bars, common in budget panels, have different expansion coefficients than copper, which can lead to loose connections. HEP often specifies copper buses for greater durability in the humid Tennessee climate.

Environmental Impact of an Electrical Panel Upgrade

Modern breaker technology minimizes phantom loads by enabling more accurate shutoff. Upgraded panels also facilitate integration of renewable energy sources and energy storage, reducing reliance on non-renewable power plants. Proper disposal of old panels—a service managed by HEP—ensures metals and plastics are recycled when possible, diverting waste from landfills.

Ongoing Maintenance Tips After Installation

• Test breakers twice per year by switching them off and on to verify operation
• Keep the panel cover closed and fastened to prevent dust intrusion
• Label new circuits promptly whenever appliances are added
• Inspect for rodent activity in basements or crawl spaces that might damage conductor insulation
• Schedule a professional infrared scan every few years to detect hot spots before issues arise

Electrical Codes and Regulations Specific to Norris

Local Amendments to the NEC

Although the National Electrical Code sets nationwide standards, Norris adopts local amendments that address regional considerations:

HEP works closely with general contractors, ensuring framing and drywall crews are scheduled after rough-in approvals to prevent rework.

Common Myths About Electric Panels

• Myth: “A breaker that never trips is good.”
  Reality: Breakers can seize or wear out; occasional testing is critical.
• Myth: “Adding a bigger breaker stops nuisance trips.”
  Reality: Over-sizing a breaker risks overheating conductors and is prohibited by code.
• Myth: “Ground and neutral are the same thing.”
  Reality: Neutrals carry return current; grounds are safety paths for fault current and must be separate in sub-panels.

Utility Coordination and Permit Process

HEP prepares all documentation required by the local utility:

• Load calculation worksheets
• One-line diagrams showing meter location, service disconnect, and grounding system
• Conductor and conduit sizing tables

The utility company may install a larger meter socket or upgrade service drop conductors when panel amperage increases. HEP’s planning avoids delays by reserving crew slots weeks in advance.

Solar-Ready and Battery Backup Integration

Bus Rating Considerations

When solar backfeed is anticipated, HEP specifies load centers with bus bars rated at least 225 amps, allowing the common 120% rule for solar breaker placement.
