TA-300-I
SPEC LINK:
Yes. The ILSTA-250-I's tin-plated aluminum body is compatible with both aluminum and copper conductors ranging from #6 AWG up to 250 MCM. The tin plating helps prevent galvanic corrosion when connecting dissimilar metals, though best practice is to apply an appropriate anti-oxidant compound on aluminum conductors before termination.
The ILSTA-250-I uses a 5/16 in. bolt for mechanical termination. Always refer to the ILSCO cut sheet (linked in the product specs) for the manufacturer's recommended torque value for your specific conductor size, and follow CSA/CEC requirements for the installation. Using a calibrated torque wrench is strongly recommended to ensure a secure, code-compliant connection.
The ILSTA-250-I is CSA listed, making it acceptable for use in Canadian electrical installations including service entrances and meter bases. For outdoor or wet-location applications, ensure the enclosure or equipment it is installed in provides the appropriate environmental protection rating (e.g., NEMA 3R or 4), as the lug itself is not independently rated for direct exposure to the elements.
