[QUOTE="four_engines, post: 393494, member: 26321"] Hello everyone! Need as much advice as I can get. This issue has stumbled a few certified electricians. Hopefully, with the wealth of knowledge here, a solution to this can be found. I'm a homeowner and a fairly competent DIYer. My home was meant to be set up to have 2 points of 2-way (aka 3-way in the US?) heater switches connected to a conventional storage-type water heater placed in the roof area during a renovation, which was completed about 3 years ago. However, every year of so since, one or both of the switches would malfunction. Upon inspection, one of the parts on the inside would be melted. At each of the point, there are 3 sets of E, N and L wires coming out of the wall. Totalling of 9 wires per point. Unfortunately, I don't have the wiring diagram. I would like to assume that they are wired "correctly" between each of the 2 points and the water heater. I'm using Schneider Electric's Vivace series KB31D20NE_2, which is described as "20A 250V 1 Gang 2 Way Double Pole Switch with Neon and Earth", for both. I assume they are DPDT switches. The back of each switch looks like this. o L1 o L2 o L3 o NEON o N1 o N2 o N3 o NEON o E How should the switches be wired so that they will not melt and still allow me to turn on the heater from either of the 2 points, complete with neon light indication.
