Can ACSS hardware (dead-ends, splices, etc) be used with ACSR conductors?
Usually you can, but the converse is never true – most ACSR hardware cannot be used on ACSS due to the higher operating temperature and current load carried by ACSS (see Is ACSS hardware the same as ACSR?). In fact, some companies that use both types of conductor have standardized on ACSS hardware to reduce cost and prevent confusion. Check with your hardware manufacturer for their recommendation.
