UL File # E5238

Yes, many of our connector models are manufactured in Canada. This includes our most popular twist-on connector, Can-Twist®, as well as the Canadian WireTwist® family, to name a few.

We’re sorry, but this item has been discontinued with no replacement. We apologize for any inconvenience.

Aluminum wiring is known for overheating. That’s why building codes no longer allow it. When aluminum wiring rusts, the white oxide is not a very good electrical conductor. It interferes with the flow of electricity and can cause overheating. These connectors are plastic, so overheating would be a very serious issue. If you have aluminum wiring in your house, it is still safe provided you use proper connectors and connection methods to switches and receptacles.

No, they would need to be concealed in an outdoor-rated box.

With solid wires, yes. Just twist and pull and they can be removed. With stranded, no, as strand will break off inside the connector. If you plan on removing the connector from stranded copper, our lever-style connectors would be the best option.

B-TAP® model numbers BTC 2/0-14, BTC4/0-10, BTC1/0-10, BTC500-14, and BTC250-6 connectors have been tested and successfully passed the new requirements in UL 486A-B for the marking “Suitable for Use on the Line Side of Service Equipment”.  The testing has been acknowledged by Underwriter’s Laboratories and is now part of the UL Listing for the IDEAL file E5238. Please note that no changes to the existing connectors in the market were required to meet the Line Side requirement.
