a. Green finish
b. Included in the manufactures instructions
c. Use
d. Laboratory approval

Answer 1

Type 3 Surge Protective Devices can be installed on the load side of a branch circuit overcurrent device up to the equipment served. However, if the connection is made in this manner, it must be a minimum of 30 feet away from the service or separately derived system disconnect. The correct option is c. Use.

Step-by-step explanation:

Surge Protective Devices (SPDs) are used to protect electrical systems from voltage spikes or surges. Type 3 SPDs can be installed on the load side of a branch circuit overcurrent device up to the equipment served. However, if installed in this manner, the type 3 SPD connection must be at least 30 feet away from the service or separately derived system disconnect. This is to minimize the risk of the SPD causing unintended disturbances in the electrical system.

For example, if you have a type 3 SPD installed on a branch circuit that serves a piece of equipment, the connection should be at least 30 feet away from the main disconnect that supplies power to the entire system. This helps ensure that the SPD doesn't interfere with other devices or cause issues with the electrical system as a whole.
