I bought this isolator switch for my Tesla Wall Connector/Charger. I live in the United States and it's very difficult to find these nice isolator switches here. They tend to use the ugly archaic metal disconnect boxes here which aren't designed to be used on a regular basis. So I found "electricalworld" online. They have a very extensive range of equipment and just the switch I was looking for. Ordering and payment online was seamless and they shipped the product from their location in Ireland and it reached me here in North Carolina in just 4 days. I couldn't get anything from California any faster than that. I highly recommend ElectricalWorld and look forward to my next business transaction with them.
