Do hand dryers in a bathroom need a GFI breaker?
In general, hand dryers in a bathroom do not require a GFCI breaker specifically for the hand dryer itself. However, GFCI protection is required for outlets in bathrooms to ensure safety from electrical hazards, so the outlet where the hand dryer is plugged in should be GFCI protected according to electrical codes.
Does a GFCI need to be on an independent circuit?
No, it can be on a circuit with conventional outlets.
How many elec outlets can a GFCI detect?
A GFCI can detect ground faults on the specific circuit it is connected to. If multiple outlets are on the same circuit protected by a single GFCI outlet, the GFCI can protect all of them. However, if the outlets are on different circuits or not downstream from the GFCI, they would need their own GFCI protection.
Do both the breakers and the outlets need to be GFI if you are running two 15 amp GFI circuits?
If you're using a GFCI breaker then the entire circuit will be protected by just the breaker alone. Every receptacle, switch, etc on that breaker will utilise the GFCI protection. You may have problems with it tripping if you plug in a motor (vacuum, etc) on the circuit.
Will GFCI prevent surge damage?
No, GFCI (Ground Fault Circuit Interrupter) outlets are designed to protect against electrical shock hazards, not surge damage. For surge protection, you would need to use surge protectors or whole-house surge protection devices.
