Product FAQs
8 answersHow should I use the 15A rating when selecting the Siemens B315GFHH?
The 15A rated current guides load and conductor selection. Apply the circuit's load-sizing and conductor-ampacity requirements rather than treating 15A as an allowable continuous load in every application.
What circuit requirements should I check against its voltage rating and pole count?
This breaker has 3 poles and a 208Y/120VAC rating. Select it for a circuit requiring three-pole protection at that rated voltage.
How does the 65kAIC interrupting rating affect selection?
The 65kAIC rating describes the breaker's ability to interrupt short-circuit current. Available fault current at the installation point must not exceed that rating at the applicable rated voltage.
What protection does the GFCI feature add?
GFCI protection detects current imbalance associated with leakage outside the intended circuit path and interrupts the circuit. Choose this feature when ground-fault circuit-interrupter protection is required.
How does the thermal-magnetic trip respond to overcurrent?
The thermal element responds to sustained overloads, while the magnetic element responds rapidly to high short-circuit current. This combines overload and short-circuit protection in one breaker.
What does the pigtail neutral mean for installation?
The neutral connection uses a pigtail lead. Plan to connect that lead to the system neutral as part of the GFCI wiring.
What conductor sizes can I terminate on the load side?
The conductor range is 14-6 AWG, and the load-side connection uses a lug. Select a conductor within that range that also meets the circuit's ampacity requirements.
How does the 60/75 °C conductor temperature rating affect wire selection?
Use the 60/75 °C conductor temperature rating when checking allowable conductor ampacity. A conductor's higher insulation temperature rating alone does not permit using a higher ampacity at the connection.
