Entering the Building & the Service Head

2026 NEC References: 230.52, 230.53, 230.54

🎯 What You'll Learn

This is where the service conductors transition from the outside world into the building.

💧 DRIP LOOPS

Individual open conductors entering a building use appropriate entry methods and require a drip loop.

The goal is straightforward:

Keep water from following the conductors into the raceway or equipment.

🔧 SERVICE RACEWAYS

Exposed raceways carrying service-entrance conductors need to be suitable for wet locations and arranged so water can drain.

The same basic concern applies to raceways embedded in masonry.

🏠 SERVICE HEAD

A service raceway connecting to overhead service conductors requires a suitable service head.

SE cable has corresponding requirements, including an allowed gooseneck arrangement under the applicable conditions.

The service head or gooseneck is normally above the attachment point.

When that isn't practical, it can be located within:

24 inches (600 mm)

of the attachment point.

🧠 EXAM-STYLE QUESTION

If it's impractical to put the service head above the point of attachment, how far below it can it go?

Answer: Not more than 24 inches (600 mm).

📌 QUICK TAKEAWAY

Water and electricity don't mix.

Article 230 pays close attention to drainage, drip loops, service heads, and building entries.
