Is it 3-phase or single-phase boiler? Why 3 wires coming to heating elements on bottom, but power comes to boiler through 2 wires on top? Or hot wire is connected to 2 parralel heating elements and neutral wire connected to one heating elements series to two previous elements (1.5 of real power)? But where is bridge from hot wire to second heating element? And how ground wire is connected here? Dmitry G (talk) 20:42, 22 June 2011 (UTC)[reply]
