Dear Sir,

 

We wanted to mark the boundary in the floor for Limited approach, Restricted approach & Flash hazard boundary in all our MCC / LCC rooms,

 

Kindly suggest the color code for floor marking tapes for marking the same, 

 

Also the distance for marking the limited approach boundary is 1.0 Meter ( for 151 V-750 V) and restricted approach boundary is 0.3 Meter (  for 151 V-750 V ) ,

 

kindly suggest from which point of panel encloser this distance needs to be calculated ?
