What voltage and type of receptacle outlet should be provided adjacent to the equipment?

The correct choice indicates that a 120 volt AC grounding receptacle outlet should be provided adjacent to the equipment. This is appropriate because most low-voltage equipment and tools commonly used in oil fuel applications are designed to operate on a standard 120 volt AC supply. Using a grounding outlet is crucial for safety, as it helps to discharge any build-up of electrical static and provides a safe path for electricity to ground in case of a fault.

Grounding is particularly important in installations where there may be exposure to moisture or conductive materials, which is common in oil fuel environments. Therefore, having a grounded outlet reduces the risk of electrical shock and improves overall safety.

While other options may reflect different voltages or configurations, they might not be suitable for the types of tools or equipment that are typically utilized. For example, 240 volt options are more suited for heavy machinery or larger appliances, and DC options are less common for standard household or light industrial equipment in this context.
