Current Requirement

Yes, the 2020 National Electrical Code (NEC) requires all GFCIs installed in bathrooms to be tamper-resistant (TR). This is a requirement for both residential and commercial buildings.

Purpose of Tamper-Resistant GFCIs

TR GFCIs are designed to prevent children from tampering with the internal components of the device and potentially receiving electrical shocks. They do this by using special screws or mechanisms that make it difficult for children to access the hazardous areas of the GFCI.

Implications for Two-Wire Devices

TR GFCIs do not accept two-wire devices (e.g., appliances with ungrounded plugs) because these devices are not designed to protect against ground faults. When a two-wire device is plugged into a TR GFCI, the GFCI will trip and cut off power to the device.

Solution

If you are having trouble plugging your two-wire devices into the TR GFCI in the bathroom, you have two options:1.

Use an adapter

You can purchase an adapter that will allow you to plug two-wire devices into a TR GFCI. However, it's important to note that using an adapter does not provide the same level of protection as using a three-wire device or a GFCI with a test button.2.

Install a non-tamper-proof GFCI

You can replace the TR GFCI with a non-tamper-proof GFCI. This will allow you to plug two-wire devices into the outlet, but it will not provide the same level of protection against electrical shocks as a TR GFCI.

Recommendation:

For optimal safety and compliance with the NEC, it is recommended to keep the TR GFCI installed in the bathroom and use an adapter for two-wire devices. Flag for review
