⚡ NEC Article 120 — Load Calcs Won't Kill You

🏥 Episode 41 — Hospital Receptacles Get Their Own Discount Table

Article: 120 — Load Calculations
Part: Part VI — Health Care Facilities
Section: 120.110
Format: Quick Hit

🎯 What You'll Learn

Health care facilities have their own special receptacle-load demand factors.

Section 120.110 allows certain receptacle loads to be subjected to Table 120.110, creating a different calculation method from the general non-dwelling receptacle rules covered earlier in Article 120.

📖 The Quick Hit

🏥 Health Care Facilities

In health care facilities, receptacle loads calculated under:

• 120.14(H) — Fixed multioutlet assemblies

• 120.14(I) — Receptacle outlets

can be subjected to the demand factors in Table 120.110 when the branch circuits are 150 volts to ground or less.

Why does that matter?

This isn't simply another application of the general receptacle demand-factor table.

Health care facilities have their own specific provision and table.

📊 Table 120.110

The table begins with a familiar concept:

First 10,000 VA or less

➡️ 100%

There is no demand-factor reduction applied to the first 10,000 VA.

Remainder over 10,000 VA

➡️ Demand factor not available in the source material used for this Quick Hit

⚠️ Source note: The supplied source text does not contain the percentage for the "Remainder over 10,000" row.

Rather than guessing at an NEC value, this series leaves the missing percentage clearly identified until the complete table can be verified.

🔄 Compare It With 120.47

Earlier in the series, we looked at Table 120.47 for certain non-dwelling receptacle loads.

That table also uses a structure where:

Initial load → 100%

Additional load → reduced demand factor

The important lesson isn't to assume the tables are interchangeable.

Always check the applicable section and table.

Different occupancies can have different demand-factor rules.

🧠 Exam Takeaway

When you see 120.110, remember:

🏥 Health care facility

🔌 Receptacle loads from 120.14(H) or 120.14(I)

⚡ 150 volts to ground or less

📊 Table 120.110

And the first 10,000 VA is calculated at 100%.
