Which of the following is a safety issue when installing electrical components on a boat?

When considering safety issues in the installation of electrical components on a boat, all the provided options highlight critical aspects that can compromise the electrical system's performance and safety. Overloading circuits is a significant concern because exceeding the rated capacity of a circuit can lead to overheating, potentially causing wires to melt or electrical fires, which poses a severe safety hazard on a vessel.

Using too many connectors can also be detrimental, as they introduce additional points of failure and increase the risk of poor connections, which can lead to arcing, heat generation, and further increase the likelihood of electrical fires.

Ignoring power requirements is another major safety issue; it can result in improper sizing of circuit components, leading to malfunction or damage. Electrical devices and components have specific power ratings, and neglecting to adhere to these can result in inadequate performance or catastrophic failure.

Thus, the answer that encompasses all of these potential hazards reflects a comprehensive understanding of the safety issues that arise when installing electrical components on a boat. Each of these concerns plays a role in ensuring that the electrical system operates safely and effectively, reinforcing the necessity for attentive installation practices.
