On a single-phase circuit it can still be used by wiring the poles in series or in pairs, depending on the installation.\"}}, {\"@type\": \"Question\", \"name\": \"What is the difference between the AC and DC versions?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"DC current does not pass through zero like AC does, so an arc is harder to extinguish. The DC isolators (WRS4P32DC and WRS4P40DC) are built and rated for 1000V DC and are the ones to use on the DC side of a solar PV installation. Do not use an AC-rated isolator on a DC circuit.\"}}, {\"@type\": \"Question\", \"name\": \"Which amp rating should I choose?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Pick a rating equal to or above the maximum load of the circuit it isolates. For a typical single EV charger, the 32A or 40A model is the usual fit. For board-level isolation, look at the 63A to 125A models.\"}}, {\"@type\": \"Question\", \"name\": \"Is this a replacement for a circuit breaker?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"No. An isolator disconnects, but it does not protect against overload or short circuit. It is installed alongside protective devices such as an MCB, RCBO or MCCB.\"}}, {\"@type\": \"Question\", \"name\": \"Can I use an isolator outdoors?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"That depends on the enclosure and its IP rating. Check the WCED data sheet for the model you choose, and fit it in a suitable weatherproof enclosure if it is going outside.\"}}, {\"@type\": \"Question\", \"name\": \"Do I need an isolator for an EV charger?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Every circuit needs a means of isolation, and many installers add a local isolator next to the charger so it can be switched off for servicing. Your electrician will confirm what the installation requires.\"}}, {\"@type\": \"Question\", \"name\": \"Who should install it?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Installation should be carried out by a competent electrician in line with BS 7671 and the manufacturer instructions.\"}}]}\u003c\/script\u003e","brand":"WCED","offers":[{"title":"AC \/ 20A","offer_id":62837588885891,"sku":"WRS4P20","price":12.95,"currency_code":"GBP","in_stock":true},{"title":"AC \/ 32A","offer_id":62837588918659,"sku":"WRS4P32","price":13.95,"currency_code":"GBP","in_stock":true},{"title":"AC \/ 40A","offer_id":62837588951427,"sku":"WRS4P40","price":16.95,"currency_code":"GBP","in_stock":true},{"title":"AC \/ 63A","offer_id":62837588984195,"sku":"WRS4P63","price":21.95,"currency_code":"GBP","in_stock":true},{"title":"AC \/ 80A","offer_id":62837589016963,"sku":"WRS4P80","price":27.95,"currency_code":"GBP","in_stock":true},{"title":"AC \/ 100A","offer_id":62837589049731,"sku":"WRS4P100","price":48.95,"currency_code":"GBP","in_stock":true},{"title":"AC \/ 125A","offer_id":62837589082499,"sku":"WRS4P125","price":51.95,"currency_code":"GBP","in_stock":true},{"title":"DC (1000V) \/ 32A","offer_id":62837589115267,"sku":"WRS4P32DC","price":27.95,"currency_code":"GBP","in_stock":true},{"title":"DC (1000V) \/ 40A","offer_id":62837589148035,"sku":"WRS4P40DC","price":31.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1033\/7545\/files\/WRS4P80-scaled-450x642.png?v=1792143553","url":"https:\/\/ecoharmony.co.uk\/products\/wced-rotary-isolators","provider":"EcoHarmony","version":"1.0","type":"link"}
