Dc Posted October 25, 2005 Share Posted October 25, 2005 Should an oil-fired boiler be powered on a separate circuit from the fusebox and if so what ampage should the disjoncter be. Any help greatly appreciated.dc Link to comment Share on other sites More sharing options...
Leschenauds Posted October 26, 2005 Share Posted October 26, 2005 Can't give you the official answer but I installed my to a 16 Amp circuit breaker in my fuse box. This should be more than enough as it only feeds the small fuel pump, the water pump and the blower fan, none of which take much current even at start up. One of the contributors to the forum 'Opel Fruit' would certainly know the definitive answer.www.leschenauds.com Link to comment Share on other sites More sharing options...
VJ Posted October 26, 2005 Share Posted October 26, 2005 IMHO a 6 amp MCB would be more than enough class Bwith a douple pole isolation switch ajacent to the Boiler Run a separate circuit in 1.5mm VJ and the Team Link to comment Share on other sites More sharing options...
Opel Fruit<P><BR>Opel Fruit, Dept. 53<P> Posted October 26, 2005 Share Posted October 26, 2005 Use a seperate 6A disjuncteur on your tableau. This should be downstream of a Type AC Diff Interrupter, although a Type A will be OK. The cabling can be 1.5mm CSA or greater. (In theory, since the combined power of the pump and boiler is only around 250W, you could use a 2A DJ, but both components are capacitor start, so you would get continual trips.) Also remember that the earth in the power wiring to the boiler is not sufficient to act as an earth bond for the pipework. Link to comment Share on other sites More sharing options...
