Blue cables may have an intermediate voltage up to ________ volts.

Blue cables may have an intermediate voltage up to ________ volts.

• A. 12 volts
• B. 36 volts
• C. 24 volts
• D. 48 volts

Answer: (B)

Blue indicates an intermediate voltage level in some safety color conventions. The upper limit for that category is 36 volts, which places it above the typical low-voltage ranges (like 12 or 24 volts) but below higher voltage levels that require stricter protections. So a blue-coded circuit is treated as intermediate voltage and may require specific insulation and safety measures set for voltages up to 36 V. The other numbers don’t fit because 12 and 24 are considered lower categories, while 48 volts belongs to a higher category with different handling requirements.
