Which of the following situations is acceptable according to electrical safety guidelines?

An open junction box in a remote area is acceptable because it adheres to specific electrical safety guidelines. According to these guidelines, junction boxes should generally be accessible and properly covered to prevent exposure to live wires and connections. However, in certain instances where the junction box is located in a remote area that is not accessible to the public or subject to accidental contact, it may be permitted to remain open. This is particularly true if the junction box does not pose a risk of human contact and is not in an area where it might be disturbed or exposed to moisture.

In contrast, having open splices in walls or junction boxes, regardless of their height, typically violates safety codes because they can create potential hazards. Open splices are unprotected areas where wires are connected without suitable insulation, which increases the risk of electrical shock or fire. Therefore, it is essential to ensure that all splices are properly enclosed to maintain safety standards.
