Common Questions
We live on a volcanic lava field hillside. Could that affect our home's electrical grounding?
Absolutely. Rocky, volcanic soil has very high electrical resistance, making it difficult to establish a low-resistance ground path required by the NEC. A standard 8-foot ground rod near the Discovery Harbour Clubhouse might be insufficient. This often requires special grounding techniques, like multiple rods or a ground ring, to ensure your grounding electrode system can safely dissipate a fault or lightning strike.
Our Discovery Harbour home was built in 2001. Why do the lights dim when the new air conditioner kicks on?
Your home’s electrical system is now 25 years old. The original NM-B (Romex) wiring from that era was installed for a different standard of appliance load. Modern 2026 demands, like high-efficiency AC units, induction cooktops, and multiple home office setups, can easily overwhelm that original 150-amp service capacity. This dimming is a clear sign your main panel's bus bars are struggling to distribute power evenly under peak demand.
Our smart TVs and computers keep resetting. Is this a problem with Hawaiian Electric or our house wiring?
Given our location, it's likely a combination. HECO's grid here faces high surge risks from frequent lightning and volcanic activity, which can send transient spikes through overhead lines. Your home's internal wiring may lack adequate whole-house surge protection at the main panel. Modern electronics are highly sensitive; protecting them requires both utility-side infrastructure and proper point-of-entry surge protection on your service mast.
We have an old Federal Pacific panel. Can our 150-amp system from 2001 handle adding a Level 2 EV charger or a heat pump?
No, it cannot do so safely. The Federal Pacific panel itself is a critical fire hazard and must be replaced before any upgrade. Even with a new panel, a 150-amp service is at the lower threshold for supporting a Level 2 charger (40-50 amps) plus a heat pump and typical household loads. A full load calculation is essential, and a service upgrade to 200 amps is a common, prudent recommendation for this addition.
What's involved in getting a permit for a panel upgrade from the County of Hawaii?
The County of Hawaii Department of Public Works, Building Division, requires a permit for any service change. As a master electrician licensed by the Hawaii DCCA, I handle the application, including the load calculations and diagrams required for 2020 NEC compliance. After the inspection, I coordinate the meter re-seal with HECO. My role is to manage this entire process, ensuring the work meets all state and county codes.
How should we prepare our Discovery Harbour home electrically for summer brownouts or rare winter storms?
Summer AC peaks strain the grid, making brownouts possible. Ensure your critical circuits are on a properly installed and permitted generator interlock kit. For winter, while freezing is rare, wind and rain can cause outages. Beyond a generator, installing a Type 1 or Type 2 whole-house surge protector is a key defense, as power restoration often comes with damaging voltage surges.
We just lost all power and smell something burning. How fast can an electrician get here?
For an emergency like that, call immediately. From the Discovery Harbour Community Association Clubhouse, I can be on Hawaii Belt Road (Route 11) and at most homes in the neighborhood within 5 to 10 minutes. A burning smell indicates an active fault that requires immediate, safe disconnection and diagnosis to prevent a fire.
We have overhead power lines coming to a mast on our roof. What are the main maintenance concerns with this setup?
Overhead service in Discovery Harbour exposes the mast, weatherhead, and service drop conductors to year-round salt air, high winds, and tropical sun. You should visually inspect for corrosion at the mast connection, cracked conduit, or vegetation interference. The utility owns the drop, but the mast assembly and its grounding are your responsibility. Ensuring these components are intact is vital for safety and reliability.
