Hello,
I have had this question for a long time. I have researched a lot on this subject but i am still confused about elevator disconnect locations.
As per NEC 620.37(NEC 2011) only such electrical wiring used directly in connection with the elevator shall be permitted inside the hoistway,machine rooms,control rooms,machinery spaces and control spaces.
Now if you have a disconnect for elevator motor and a disconnect for cab lights, can you put them in a near by electrical closet in combination with other equipment like panelboards? I guess from the code above i cant. So in that case you would be needing a small closet maybe about 30"w X 12"d closet to house those disconnects? I asked the elevator rep and he was mentioning it is okay to combine them with other equipment but i am not 100% sure on this after reading the code.
Second question is now a days with MRL elevators atleast for Schindler and KONE elevators we have a fused disconnect switch in the elev.control room or closet and then a non fused disconnect switch in the hoistway. I am not sure why you would be needing two disconnects?Can you just have one fusible disconnect at the top of the hoistway and call it a day which would eliminate the need of having a separate closet?
