You're right, NEC 2023 Article 210.8 specifically lists dryers in dwelling units, but not commercial washing machines in commercial laundromats. Here's a breakdown of why this is, and what you need to consider

Why Dryers Are Listed and Washers Aren't (Explicitly) in Dwelling Units (NEC 210.8):
Dwelling Unit Focus

NEC 210.8 primarily targets dwelling units (homes, apartments, etc.). The rationale for including dryers in dwelling units is based on the proximity to water sources (washers, sinks, bathrooms) and the potential for moisture. This is particularly true in laundry rooms which, in dwelling units, are often bathrooms.

GFCI Rationale

GFCI protection is intended to protect people from electric shock. The risk of shock is considered higher where electrical appliances are used near water.

Why Commercial Laundromats Are Different



Commercial Environment

Commercial laundromats are considered not dwelling units and often have distinct electrical code requirements compared to residential settings.

Supervision and Maintenance

Commercial settings are often subject to more frequent inspection, maintenance, and general oversight than residences. The assumption is that commercial equipment is better maintained and monitored by qualified personnel.

Equipment Construction

Commercial washing machines are typically built to higher safety standards, with better grounding and insulation, than residential models.

Dedicated Circuits

Commercial washers are usually on dedicated circuits which should reduce the risk of overloading.

GFCI Requirements for Commercial Laundromats (NEC 2023)

While NEC 210.8 doesn't explicitly require GFCI for washers in commercial laundromats, you still need to consider other parts of the code:

Article 422: Appliances Specifically Section 422.5(A) could apply, depending on the listing of the appliances and manufacturer's instruction. State and Local Amendments

Many states and local jurisdictions have amendments to the NEC. Always check with your local electrical inspector or authority having jurisdiction (AHJ) to see if they have specific requirements for GFCI protection in commercial laundromats. Some jurisdictions may require GFCI protection for all receptacles within a certain distance of water sources, regardless of whether the NEC explicitly mandates it.

Manufacturer's Instructions

The manufacturer's instructions for the washing machines themselves are crucial. If the manufacturer requires GFCI protection, you must comply with that requirement, regardless of what the NEC states (NEC 110.3(B)).

Outlet Proximity to Sinks/Water Sources

Look at the proximity of outlets to sinks and other water sources. Even if not specifically required by code, GFCI protection is always a good idea for safety when outlets are near water. If an outlet is within 6 feet of a sink it may be required to have GFCI protection.

Grounding and Bonding

Ensure proper grounding and bonding of all equipment and metal parts in the laundromat. This is fundamental to electrical safety.

In summary

While the NEC may not explicitly mandate GFCI protection for commercial washing machines in commercial laundromats, it's a nuanced situation. You

must:1. Consult the Manufacturer's Instructions

This is paramount*.2.

Check Local Codes and Amendments

Local jurisdictions often have stricter requirements than the NEC.3.

Assess Risk

Consider the proximity of outlets to water sources and the general safety environment.4.

Prioritize Safety

Even if not explicitly required, GFCI protection is a wise investment in safety where water and electricity are involved.

Always err on the side of caution and consult with a qualified electrician and your local electrical inspector to ensure your installation meets all applicable codes and provides the highest level of safety. Using a licensed electrician who is familiar with commercial installations is highly recommended. Flag for review
