We sell and rent diesel driven pumps with control panels. These panels operate off of floats that go into the water. We have two different kinds of panels - one operates of 12 Volt the other off 24 Volt. What is required in order to make our floats intrinsically safe?

Re: Intrinsic Safety Requirements

Why do you want them to be intrinsically safe? That is normally used in Classified areas to prevent explosions.

One of our customers is placing these floats in a hazzardous area (according to them) and is requiring we supply them a control panel with floats that is intrinsically safe when used in this application.

You install a IS relay. See NEC article 504. Your control panels may need to be UL listed as IS.

Re: Intrinsic Safety Requirements

Is the pump suitable for pumping flammable liquids? Is the pump itself in the classified area? Is the pump suitable for installation in a classified area?
