Electrical Service – Mast

January 6, 2009

electrical-service-mastAt the house, the service cable will attach to a metal mast and enter a conduit through the weather-head. This conduit will serve a meter base. Inspect the mast and conduit to ensure it is mounted solidly, not pulled away from the house or overly distorted. A distorted mast is usually the result of undue stress on the service drop that may have occurred due to fallen tree limbs or debris that fell on the service cable. The masts are designed to endure quite a bit of stress and strain so it was probably a significant event to pull or bend the mast before the line was snapped (if at all).  This condition needs to be corrected as this could pinch or nick the conductors in the conduit. Additionally, this distorted mast can allow moisture or varmints into the house creating more issues. Consult a professional electrician regarding repair or replacement.

Key Inspection Points

  1. Ensure Mast is secure and not pulled out of line.
  2. All roof attachments are secure and not causing leaks in the roof.
  3. Inspect for cracks or openings in the conduit that may be allowing water into the meter base.
