Advanced WiringPregunta 68 de 110
A Class 2 power-limited circuit at 30 V or less is limited to a maximum power of:
a.1,000 VA
b.250 VA
c.500 VA
d.100 VA
Explicación
Class 2 circuits are inherently limited low-energy circuits; a typical alternating-current source limit is 100 VA at up to 30 V for reliable low-energy protection.
