UL 498 Changes Taking Effect June 20, 2026: A Buyer’s 8-Point Pre-Shipment Checklist for Receptacle Orders

1) Confirm the exact standard reference on the certification record

Ask the supplier for the exact certification file number, model number, and standard reference used for the product record. For products covered by the current public UL 498 revision path, buyers should check whether the record has been updated to the June 20, 2024 revision rather than assuming a general “listed” claim is enough.

2) Verify the product record in Product iQ or the certifier’s database

UL Solutions describes Product iQ as the place to verify UL certification data on products, components, and systems. Use it to verify the exact model and manufacturer information shown on the record. If the product is certified by another NRTL, ask for the equivalent current record from that certifier.

3) Review the grounding terminal language

The Intertek SUN adds explicit wording in 29.1.4: only one grounding terminal shall be provided on a grounding-type receptacle, and that grounding terminal shall only accept a single grounding conductor rather than serving as a connection point for two separate grounding conductors.

4) Check 15A and 20A conductor markings across the product set

The public Summary of Topics identifies 15A and 20A conductor markings as one of the headline changes. Buyers should therefore check the device body, package artwork, and instruction sheet together rather than reviewing only one of them.

5) If the SKU is sold for copper-clad aluminum conductor use, ask for the updated support

The Intertek SUN adds new and revised text in 30.8.1, 123.1, and 123.5 for receptacles intended for copper-clad aluminum conductor. In other words, CCA-related requirements are part of this UL 498 revision path for the affected receptacle scope. If the product is being sold for that use case, the supporting record should match that claim.

6) Treat WR and HG as claim-specific checks, not headline June 2024 changes

UL 498 includes Supplement SD – Weather-Resistant Receptacles and Supplement SC – Hospital Grade Devices. If a SKU is marketed as WR or HG, ask the supplier for the listing support tied to that claim. These are valid UL 498 supplement checks, but they are not the headline public change items of the June 20, 2024 revision.

7) Do not mix UL 498, UL 498B, and UL 943 into one document request

UL 498 does not directly apply to devices incorporating GFCI circuitry; the UL 498 scope points those to UL 943. It also does not replace UL 498B for receptacles with integral switching means. The current public UL 498B revision has its own effective date of July 23, 2027.

8) For Canada-bound orders, verify the Canadian certification mark on the product itself

Health Canada says certification marks must appear on the product, not just the packaging. Its electrical product safety guidance also tells buyers to look for certification marks such as CSA, cUL, or cETL on products that plug into an outlet.

For Ontario, buyers can cross-check marks against the
ESA recognized approval marks page.
For code timing, official provincial pages show BC adopted the 2024 Canadian Electrical Code effective March 4, 2025, Alberta declared CSA C22.1-24 in force on April 1, 2025, and Ontario’s 2024 OESC took effect May 1, 2025.
