Is TC-ER cable acceptable in Canada? Per CSA C22.2 No. 230-17, sections 5.4.2 and 5.5.2, the test methods for TC-ER cable are described. However in the Canadian Electric Code C22.1-15, type TC-ER cable is not mentioned. Please let me know if TC-ER cable is approved for use in Canada and please cite code. Thanks.
