Supply voltage loss between MCC boards and motors will be maximum 3% 

Supply voltage loss for lighting board will be maximum 5% 

Simultaneous operating coefficient will be around 0,85. 

## 8.1.6 Marking 

Each item of equipment shall be provided with a rating plate giving the type and serial number together with its ratings and service conditions. Labels and nameplates shall be provided as necessary to clearly identify the function and circuit designation of equipment. The supply voltage shall also be written on the rating plate. All panels, switches, boxes, cables, motors etc. shall be labelled. 

All rating plates, nameplates, labels and wiring plates shall be of non-corrodible material Plastic or metal material shall be provided, not label in paper). Inscriptions shall be clearly legible from the operating distance and shall be in Turkish and English throughout. Notices indicating danger to personnel shall be in Turkish. Details and locations of all such plates, labels, etc. shall be subject to the Engineer's approval. 

Labeling will be made in board and equipment side in all cables. 

 Cable label exterior sheath will be made of PP isolation raw material, HB flammability class will be UL 94, operational temperature range is between -40/+80$^{0}$C. Length should be minimum 30 mm and width should be 10 mm. 

 Label within sheath: Resistant against slight solvent, resistant against UV lights within temperature range between -18$^{0}$C and 90$^{0}$C, it will not fade under sunlight, made of plastic alloy with thermal printed and should be resistant against water.
