Okay, let's break down the requirements for replacing your bathroom fan/lights, keeping in mind that electrical codes can be complex and vary slightly depending on your local jurisdiction. It's always best to consult with a licensed electrician in your area to ensure compliance with local codes. This is especially important in bathrooms due to the presence of water.Here's a general overview based on common interpretations of the NEC (National Electrical Code), which is the basis for most local codes in the US

1. AFCI Protection:
Generally Correct

Since you're replacing existing fans and not extending the circuit, AFCI (Arc Fault Circuit Interrupter) protection may not be required solely based on the replacement. AFCI protection is more often mandated for new circuits or extensions to existing circuits, especially in bedrooms.

However

Some jurisdictions are adopting newer versions of the NEC that may require AFCI protection even for replacements. Again, check your local code!

2. Fan/Light in Shower Stall



You are Correct: It MUST be Listed for Shower Use. This is critical. The fan/light fixture must be specifically listed and labeled for use in a shower enclosure. Look for language on the fixture itself, in the manual, or on the manufacturer's website that explicitly states it's suitable for wet locations and shower/tub environments. If it doesn't say that, don't use it in the shower. GFCI Protection: You are Correct. Any 120V receptacle or equipment in a bathroom or serving a bathroom MUST be GFCI protected. The fan/light must be on a GFCI-protected circuit. This can be accomplished in one of three ways: GFCI Circuit Breaker

The breaker in your electrical panel that feeds the fan/light is a GFCI breaker.

GFCI Receptacle Upstream

A GFCI receptacle is installed upstream of the fan/light (in the same bathroom or another location on the same circuit) and protects the wiring to the fan/light. The load side of that GFCI receptacle must feed the fan/light.

GFCI Switch

Some manufacturers have made switches that are also GFCI outlets. If it meets the necessary requirements, this is also a possible solution.

Key Considerations and Cautions



Local Codes Prevail

Always, always check your local building codes and electrical codes. Call your city or county building department or consult with a licensed electrician in your area. They can provide the most accurate and up-to-date information for your specific location.

Manufacturer's Instructions

Follow the manufacturer's instructions for installation. This is essential for safety and to ensure the fixture operates correctly and complies with its listing.

Wiring



Check the wiring

When you remove the old fans, carefully inspect the wiring. Look for any damage, frayed insulation, or loose connections. Repair or replace any damaged wiring.

Use proper wire connectors

Use appropriate wire connectors (e.g., wire nuts) and ensure they are properly tightened to create secure and safe connections.

Grounding

Proper grounding is crucial. Ensure the fan/light is properly grounded according to the manufacturer's instructions and local codes. If your existing wiring doesn't have a ground wire, you may need to consult with an electrician to determine the best and safest way to ground the new fixture.

Ventilation

Make sure the exhaust fan is properly ducted to the outside. It should not vent into the attic or another enclosed space. A properly sized duct and a direct vent to the outside are essential for effective moisture removal.*

Amperage: Ensure that the amperage of the new fan does not exceed the amperage of the breaker or the wire size. If the new fan requires more amperage, you will have to upgrade the wiring, which would no longer qualify as a replacement but a modification.

In Summary


Double-check local codes for AFCI requirements, even for replacements.2. The shower fan/light MUST be listed for shower use (wet location).3. The shower fan/light MUST be on a GFCI-protected circuit.4. Follow manufacturer's instructions meticulously.5. Inspect existing wiring and make necessary repairs.6. Ensure proper grounding.7. Vent the fan to the outside.8. Consult with a licensed electrician if you have any doubts or questions.
