2026 NEC References: 230.70(A)(2)–(3), 230.70(C)–(F), 230.71

🎯 What You'll Learn

The location and number of service disconnects depend on the type of installation.

📍 LOCATION

For installations other than one- and two-family dwellings, the service disconnect is located in a readily accessible location.

It can be outside or inside nearest the point where the conductors enter.

Service disconnects are not permitted in bathrooms.

⚡ OTHER POWER SOURCES

Where generators, solar systems, or other energy sources aren't disconnected adjacent to the service disconnect, a plaque identifies where those disconnecting means are located.

🔢 HOW MANY?

The default is:

ONE service disconnect.

But qualifying installations can have:

2 through 6

service disconnects.

Each disconnect must be arranged in an appropriate enclosure, switchboard section, switchgear compartment, metering center compartment, or other permitted compartment.

🧠 EXAM-STYLE QUESTION

What's the maximum number of separate service disconnects allowed for one qualifying service?

Answer: Six.

📌 QUICK TAKEAWAY
