Test instruments and their accessories rated for circuits and equipment are required. UL 61010-1 addresses rating for voltage measurement equipment intended for use on electrical systems of what maximum voltage and below?

• A. 1000 V
• B. 600 V
• C. 1200 V
• D. 2000 V

Answer: (A)

UL 61010-1 sets safety requirements for voltage-measuring instruments and their accessories that are used on electrical systems. It specifies the maximum system voltage that these instruments are designed to be used with. The standard covers equipment intended for use on systems up to 1000 V (AC or DC). That means instruments rated for 1000 V and below are within its scope, while systems higher than 1000 V fall outside this standard. So, the correct maximum voltage to consider for UL 61010-1 is 1000 V.
