Copper Terminal Reducer
Copper Terminal Reducer
Frequently Asked Questions
A copper terminal reducer allows a smaller-gauge cable to be safely connected to a larger stud, bolt, or busbar hole by bridging the size gap between the two, ensuring a snug, stable termination without loose fitting.
While a standard lug is designed for a matching wire-to-hole size ratio, a reducer specifically features a stepped or tapered barrel and eyelet, letting technicians adapt mismatched cable and stud sizes on site without needing a custom-made part.
They are commonly needed during panel upgrades, equipment retrofits, cable downsizing projects, or when connecting new wiring to existing busbars and studs that don't match the original cable specification.
Shree Shiva Electrical offers these reducers in bare electrolytic copper as well as tin-plated finishes, with the plated option providing extra protection against corrosion in humid or outdoor panel environments.
The current rating is generally governed by the smaller cable size at the connection, so it's important to select a reducer sized correctly to avoid overheating or exceeding the safe ampacity of the thinner conductor.
It is typically installed using a hydraulic or mechanical crimping tool suited to the barrel's inner diameter, followed by insulation such as heat-shrink tubing to cover the exposed crimped area for added safety.
