in three pin plug 6 Amp. 220v AC rating. why earth pin diameter is higher than ohter two pin? what its purpose ?
6 8963Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
HAL,
2003We have 90mX100m hangar with 16 no.of supporting pillar. It is required to provide power supply on all pillars. what is suggested earthing scheme for hangars.
HAL,
1954In a company the lines carrying 33KV but the load is below 10000Volts so we know that <11KV we can put 11KV lines but the lines are 33KV,..so how we can step down the voltage to 11KV with out erecting a substation
