If the conductors are slack, what type of connections can be used?

When conductors are slack, using bolted or squeeze-on connections is appropriate because these types of connections allow for adjustments and can accommodate movement without compromising the integrity of the electrical connection. Bolted connections provide a strong and reliable method of connecting conductors while allowing for some flexibility, which is essential when slack exists. Squeeze-on connections, on the other hand, securely grip the conductors and are particularly useful in situations where varying levels of tension might be present.

In contrast, jumpers may not be ideal since they are typically used for making temporary connections or bypassing sections and do not provide the stability needed when conductors are not under tension. The option suggesting any type of connection does not consider the specific requirements for slack conductors, as some connections may not maintain their integrity without a certain level of tension. Finally, relying solely on welded connections is unsuitable in this scenario because welds require a firm connection to work effectively and are not built to accommodate slack, making them less adaptable than bolted or squeeze connections.
