Splices, including butt splices, do not typically come with a specific current rating. Instead, they are generally rated by the wire gauge (AWG) they are designed to connect. The splice is expected to handle the same current capacity as the wire it connects, assuming proper installation and a secure connection. For example, a splice rated for 8 AWG wire would be expected to handle 40-55 amps, as that’s the typical current range for 8 AWG wire.
The logic behind this is that the splice, when correctly crimped or connected, provides continuity for the wire and does not introduce significant resistance or heating. Therefore, it is considered to have a current rating equal to or greater than the wires being spliced.
However, in certain applications, especially in high-power or industrial settings, manufacturers may provide recommendations or guidelines on the current capacity based on factors like heat dissipation, material quality, and environmental conditions.
