Customer Questions & Answers

Can I connect 8 gauge aluminum to 10 gauge copper with these wire nuts?

Asked by: WDH1
No, #8 wire will not work with these connectors as a temporary aluminum to copper splice.

Please be specific about how many you get...

What is the amount of purple connectors you get for $19?
Asked by: JSmallz
Typically you will get 2 per bag. For $19 you will get about 6 connectors. You may need more to replace the ones that burn up.

Can these be used to connect Aluminum to Aluminum # 18 wire

Can these be used to connect Aluminum to Aluminum # 18 wire
Asked by: JOhNY
No, these have never been approved for aluminum to aluminum connections and are at best good for only a temporary connection of aluminum to copper wire. It isn't likely that you have aluminum wire, but more likely it is tinned copper wire. Look closely at a cross section of the end of the wire and look for copper in the center. If it is tinned copper you should use either a 71B or 72B twist-on wire nut.

Are these twister connections approved by Underwriter Labs or the Consumer Product Safety Commission?

The consumer product safety commission specifically recommends against using twister connections when connecting aluminum and copper wire. Are these safe?
Asked by: Will
Hi Will the IDEAL Twister® AL/CU is tested to UL 486C and CSA22.2 #41-07 in order to comply with the United States National Electrical Code (NEC) and the Canadian Electrical Code (CEC). The Twister® AL/CU is also listed to UL 467 and CSA C22.2 #198.2 for grounding and bonding. The Twister® AL/CU has been UL listed and CSA certified since its introduction in 1995. The connector has successfully completed UL tests using both the “old” technology (1350) and “new” technology (8000) aluminum conductor material. Keep in mind the connectors can only be used once since the compound on the inside will come out if you remove the connector. Hope that helps Ron at

Customer Reviews

Twister Al/Cu Wire Connectors, 65 - Purple (2 per Bag, Standard Package is 4 Bags) is rated 4.0 out of 5 by 2.
Rated 3 out of 5 by from Better than nothing For alum wiring, better than reg connectors, but not better than screw type alumconn connectors. Some folks have trouble with these with copper and alum. Probably good for stranded wire such as installing a ceiling fan or outside light.

Rated 5 out of 5 by from great for my project I was updating switches for a mobile home with aluminum electrical wiring and I needed a fix for any switch that might cause a concern with a fire threat. After doing some research, I found these connectors were recommended to splice a copper wire to an aluminum wire. I did not want to rewire the mobile home from aluminum wire to copper because of the expense. These connectors did the job much cheaper and in less time. The connectors made it difficult to fit the switch into the box, but after some patience and some adjustments with the placement of the nuts, wires, and switch the job was finished successfully.
