Can you use these connectors to connect aluminum wire to Copper wire ?

You could use these connectors for almost anything, but *should* you use them? NO!! If you have a home with aluminum wiring, you really should replace it as soon as you can. Aluminum wire is a clear and present danger if found in homes. Its not a job people should tackle themselves too. Hire a professional to replace/rewire. Also, each device should have a ground wire too. Many aluminum wired houses I've run into also end up with no grounds at outlets, so rewiring can fix two things at once.

How many connectors are in the box? Pro tip for the seller... You may want to lead with this information.

画期的製品で作業性向上しました。

価格は高めです。本製品で1本の配線を延長接続する場合、1個のコネクタ96円程度必要。対して従来使用していたニチフのピン端子の場合、オス、メスそれぞれ1個ずつ必要で合計50円程度と見かけは安い。しかし、本製品を使用する場合、工具はワイヤーストリッパだけで良く、圧着ペンチは不要です。以前使用していたピン端子の圧着しにくいSMCのオートスイッチ細線も、本製品なら誰でも簡単に接続できます。接続状態も透明カバーなので目視で確認できる。0.3SQから3.5SQまでが接続できるので、何種類もピン端子を在庫しなくて済みます。しかも再利用が可能！ここが最大のメリットかも。アマゾンなら似たようなコネクターもありますが、FA用途の場合一流メーカーの製品を使いたいですね。WAGOなら安心して使用できます。
