Oil Boiler Isolation Switch.

Zoomup over 5 years ago

Evenin' All,

Regarding an external ground sited domestic oil fired boiler for heating and hot water that has an internal switched fused connection unit nearby inside the house, what regulations will require an external electrical isolator adjacent to the oil boiler? You know the sort of thing, a double pole rotary isolator.

so 510.3 if the MIs stipulate

132.15.201 if necessary to remove danger

And possibly, if it has an electric motor, 132.15.202

There is no indication in the manufacturer's instructions to fit an external isolator. Any motor is safely encased and contained so is totally inaccessible by anybody as it is inside a substantial housing as the oil boiler is located outside the house.
