Question: This picture was in the WA State Currents newsletter picture of the month. Taken by an inspector, the question is asked what article 230 section is the installation a violation of?
Without seeing the picture, it's impossible to give a definitive answer and cite the specific section of NEC Article 230 that the installation is violating. However, I can give you some common scenarios that inspectors find and the corresponding sections in Article 230 of the National Electrical Code (NEC)
Common Scenarios and Potentially Relevant Sections:
Insufficient Clearance over Driveways/Roadways
Likely Violation
NEC 230.24(B) - Minimum clearance for service conductors over driveways, roads, and other areas subject to truck traffic. This is a very common violation.
Insufficient Clearance over Pedestrian Areas/Roofs
Likely Violation
NEC 230.24(A) and (E) - Specifies minimum vertical clearances for service conductors above sidewalks, ground, roofs.
Service Conductors Not Protected from Physical Damage
Likely Violation
NEC 230.50 - Requires service conductors to be protected from physical damage where exposed to it. This could involve conduit, guard strips, or location.
Improper Point of Attachment
Likely Violation
NEC 230.26 - Point of attachment shall be located at or above the minimum clearances required in 230.
24.
Service Head/Drip Loop Issues
Likely Violation
NEC 230.54 - Details requirements for service heads and drip loops to prevent water from entering the service raceway or equipment.
Improper Service Grounding
While grounding is primarily addressed in Article 250, the service grounding electrode system is connected at the service equipment. Violations related to the grounding electrode conductor (GEC), its size, or connections can occur here.
Likely Violation
Technically, the issue is in Article 250, but the physical connection is often visible at the service.
Service Entrance Conductors Not Properly Sized
Likely Violation
While sizing is covered throughout the NEC, if the service conductors are visibly undersized for the calculated load, it could be a violation of NEC 230.42.
Service Disconnecting Means Not Readily Accessible
Likely Violation
NEC 230.70(A)(1) requires the service disconnecting means to be readily accessible.
Service Disconnecting Means Not Properly Rated
Likely Violation
NEC 230.79 Specifies the minimum ampacity rating of the service disconnecting means.
What to look for in the Picture (if you can remember)
Overhead Service Drop
The height of the wires above the ground or roof.
Service Head
The fitting at the top of the service mast where the wires enter the building. Is it damaged? Is it sealed properly?
Service Mast
The pipe supporting the overhead service conductors. Is it properly supported? Is it rusted?
Conduit/Raceway
The pipe or channel protecting the service wires. Is it damaged? Is it properly secured?
Grounding Electrode Conductor (GEC)
The wire connecting the service equipment to the grounding electrode (ground rod, water pipe, etc.). Is it properly sized? Is it protected from damage?*
Service Disconnect
The main breaker or switch. Is it accessible? Is it clearly labeled?
