One of the foremost challenges for cabling teams is voltage drops that can occur in long runs. Companies are now specifying oversized copper cables to mitigate these voltage drops. But these copper cables must then be sized down at the end to fit into the equipment lug or circuit breaker. And so now teams must use compression adapters to overcome the difference in cabling sizes. In this post, we’ll explore how compression adapters are being used in copperor aluminum wire applications.

How compression adapters work

Compression adapters serve as a transition from aluminum or copper cable to smaller pin for insertioninto lugs or circuit breakers. The products use an aluminum compression barrel and a Class-B stranded copper cable pin. They are dual-rated for installation on either aluminum or copper cable.

Specific applications

There are specific applications that require the use of compression adapters. For example, for standard Class-B copper wire companies can use the PT-R ReduceR™ Step-Down Adapters. There’s also the PT-FX Shoo-Pin™ Flex-cable Adapters, which are designed for optimal performance with flexible, high strand copper wire. All-copper compression adaptors are widely recommended to install on a Class-B cable or various styles of flexible high-strand copper cable.

For both for moderate or extreme aluminum-to-aluminum or aluminum-to-copper reductions, dual-rated one-piece aluminum compression AC-R Reducing Splices are a leading-class option. Companies might also use ACK kits, which consist of an aluminum barrel splice, and copper CRA adaptor inserts.
