Ground Fault Circuit Interruptor (GFCI)Updated a year ago
Understanding Mysa In-Floor's GFCI Type
- Type of GFCI
- Mysa In-Floor uses a 5 mA Class A Ground Fault Circuit Interrupter (GFCI), essential for safety.
- Role of GFCI
- This device protects your floor heating system from power surges and other electrical issues. In North America, GFCI's are commonly installed in homes as a safety standard. Class A GFCI's can shut off power with only 5 mA of leakage, providing efficient fault detection.
Built-in GFCI in Mysa In-Floor
- GFCI Inclusion
- Mysa In-Floor incorporates a Class A GFCI within the thermostat, eliminating the need for a separate GFCI-protected circuit.
- Non-Disablable Feature
- The GFCI in Mysa cannot be disabled, ensuring continuous protection.
GFCI Specifications in Mysa In-Floor
- GFCI Rating
- Mysa is equipped with a Class A 5 milliamps (mA) GFCI.
- Compatibility
- It's not suitable as a replacement for thermostats with a 15 mA GFCI due to differing trip levels.
Installation Considerations for Mysa
- Circuit Panel Compatibility
- Installing Mysa on a circuit with an existing GFCI breaker is not recommended as it may cause false trips. Consider using a standard breaker for Mysa installations.
- Class B GFCI Replacement
- Mysa cannot replace thermostats with a built-in Class B GFCI (15 mA trip level) as this would likely lead to frequent tripping of Mysa's internal GFCI, which has a lower trip level of 5 mA.
