Ohio Electrical Contractor NEC Code and Safety Standards Practice Test

For Condition 3 equipment operating at a maximum of 1000 volts, the National Electrical Code (NEC) specifies that the minimum working space depth should be 3 feet in front of the equipment. However, since the question refers to the specific context of Ohio's electrical regulations and might incorporate local amendments, it can sometimes be aligned differently based on professional judgment or additional state regulations.

The choice of 2 feet as a minimum working space may arise from a misinterpretation or from confusion with other codes or conditions; however, in general practice and adherence to the NEC, 3 feet is often regarded as the standard requirement for adequate safety and accessibility to the equipment, allowing personnel enough working space to perform maintenance or inspections safely.

In the broader context of electrical safety, ensuring that there is sufficient space not only protects the workers from the potential hazards associated with high voltage but also complies with necessary clearances and access for emergency situations. Therefore, the correct minimum depth of working space is critical to maintaining both safety and compliance with the standards.
