What maximum voltage is considered a low voltage contact limit for continuous DC?

• A. 15 volts
• B. 30 volts
• C. 21.2 volts peak
• D. 12.4 volts peak

Answer: (B)

The maximum voltage considered a low voltage contact limit for continuous DC is 30 volts. This standard is established to differentiate between low voltage and higher voltage systems, as higher voltages can pose greater risks for electric shock or associated hazards. In practical applications, understanding this limit is crucial for safety regulations and ensuring compliance with electrical codes. The 30 volts threshold is typically accepted in many electrical standards, including those used in the residential appliance installation context, to categorize what constitutes a low voltage circuit. By staying within this limit, installers and technicians can better ensure safe handling and installation of appliances that operate at low voltage levels, thereby minimizing the risk of harm to personnel and damage to equipment.
