Wires may be spliced in a wireway, provided that _______?

Wires may be spliced in a wireway, provided that they will be accessible later. This requirement is crucial because it ensures that any future maintenance, troubleshooting, or inspection tasks can be performed without difficulty. Accessibility guarantees that anyone working on the electrical system can easily reach the splices, which is essential for safety and compliance with electrical codes.

Accessibility is a core principle in electrical installations, where safety and efficiency during maintenance is prioritized. If splices are made in hard-to-reach places, it could lead to hazardous situations during repair work or future modifications, increasing the risk of accidents or code violations.

While securely taping wires, ensuring they are properly color-coded, and meeting voltage ratings are important aspects of wiring and splicing, they do not directly address the need for future access, which is the key factor in this requirement.
