Hi,
I would like to know if the sealing fitting is required in the following cases:-
1- the motor is explosion proof but is has internal switch(thermostat switch) !!!!
2- the switch(pressure switch) is certified as explosion proof switch but these is no label on the switch to indicate that it is factory sealed switch !!!
3- do we need to add sealing fitting to the terminal box(junction box that has only terminasl to connect the wires) ???(that does not has make and break or high temp ??
Thanks..
