Healthcare facilities are one of the more nuanced spaces to design under the National Electrical Code, and the NEC 2026 brings meaningful changes to how you calculate receptacle loads in these buildings. If you’ve worked with healthcare receptacle demand factors before, you’ll want to understand what moved, what got renamed, and, most importantly, what changed in the math.
Renumbering
The first thing to know about the NEC 2026 is structural. All the feeder and service load calculations that lived in Article 220 in the 2023 edition (and every edition before it) have been relocated to the new Article 120. The codes themselves are largely the same set of rules; they’ve simply been moved and renumbered.
For healthcare facilities, that means the section you may know as 220.110 is now 120.110. The content is the starting point, but as you’ll see, the healthcare receptacle rules didn’t just move; they were rewritten.
Healthcare Receptacle Load History
It’s easy to assume healthcare receptacle demand factors have always been in the code, but they haven’t. This section is genuinely new as of NEC 2023. In the 2020 edition and earlier, there was no dedicated healthcare facility receptacle load calculation; those receptacles were simply treated like any other non-dwelling unit receptacle load.
We’re really looking at a rule that only existed for two code cycles, and it changed significantly between them. Understanding both editions matters because many jurisdictions are still on NEC 2023, while others begin adopting NEC 2026.
NEC 2023 Healthcare Receptacle Loads
The whole reason this section was created in 2023 was to give healthcare receptacles a lower demand factor than a standard non-dwelling unit receptacle load. The logic: not every receptacle in a hospital is in use at once, and the code recognizes that with more favorable demand calculations.
NEC 2023 split healthcare receptacles into two demand factor tables based on patient care space categories. Those categories don’t come from the NEC itself; they’re defined in a separate standard, NFPA 99, Section 4.1. The categories correspond to the risk to the patient if power fails:
- Category 1 – Failure could cause death or major injury
- Category 2 – Failure could cause minor injury
- Category 3 – Failure causes patient discomfort
- Category 4 – No danger to the patient
High-Risk Spaces: Table 220.110.1 (Categories 1 and 2)
For the high-risk patient care areas, NEC 2023 applied an aggressive, favorable demand schedule:
- First 5 kVA at 100%
- 5 to 10 kVA at 50%
- Over 10 kVA at 25%
That 25% over 10 kVA is notably lower than the 50% you’d apply to a standard non-dwelling unit receptacle load, a real benefit for the most critical spaces.
Low-Risk Spaces: 220.110.2 (Categories 3 and 4)
For the low-risk patient care areas, the demand factor simply matched a standard non-dwelling unit receptacle:
- First 10 kVA at 100%
- Everything after at 50%
In short, NEC 2023 carved out the high-risk patient care spaces and gave them a break, while leaving low-risk spaces on par with ordinary commercial receptacles.
What Changed in NEC 2026
NEC 2026 moved everything from Article 220 to Section 120.110, but it also rethought the entire approach. The references to NFPA 99 patient care categories are gone. Instead of organizing by risk category, the 2026 edition splits healthcare receptacles into two practical groups: general-purpose receptacles and specific patient care-related electrical equipment.
General-Purpose Receptacles: Table 120.110
For general-purpose healthcare receptacle loads, the demand factor is now:
- First 10 kVA at 100%
- Everything after at 20%
That 20% tail is even more favorable than what most designers are used to.
Specific Equipment: Section 120.111 (A New Approach)
Here’s the most significant shift. For healthcare facilities and patient care-related electrical equipment, NEC 2026 stops basing the calculation on load (kVA) and instead bases it on the number of circuits:
- First 10 circuits at 100% demand
- After that, each circuit at 30%
This is a genuine change in methodology. If you’re calculating specific equipment receptacle loads under NEC 2026, you’re counting circuits, not totaling kVA.
You May Have Three Types of Receptacle Loads in One Facility
One practical point that’s easy to overlook: these healthcare receptacle rules apply specifically to receptacles in healthcare settings. A single building can contain a mix.
Imagine a facility with patient care spaces, specialized medical equipment, and shared office space. You could legitimately end up calculating three separate receptacle loads in the same building:
- Standard non-dwelling unit receptacles (formerly Article 220, now 120.47) for the office and general commercial areas
- General-purpose healthcare receptacles under Table 120.110
- Specific patient care equipment receptacles under Section 120.111
Keeping these straight is essential for an accurate feeder and service load calculation.
Key Takeaways for NEC 2026 Healthcare Load Calculations
- Feeder and service load calculations moved from Article 220 to Article 120 in NEC 2026.
- Dedicated healthcare receptacle rules are new as of NEC 2023; they didn’t exist in 2020 or earlier.
- NEC 2023 organized healthcare receptacles by NFPA 99 patient care categories (1–4) across two demand tables.
The net effect is that the NEC has continued to refine how healthcare facility loads are treated, generally trending toward lower, more realistic demand factors.
