Hi.....first of all I'd like to say thank you for allowing me to join the forum.....I'm a third year student and have giving a task of drawing a EARTH FAULTLOOP PATH FOR A COOKER CIRCUIT in a house. I'm stuck on the cooker circuit part....please please help. Cheers Mike
 
just treat it as a radial. imagine L-E shorted at the cooker and draw the fault path from the L at supply, to the cooker, then back down the cpc to the supply earth.
 
If you have an 'On Site Guide ', this is an IET publication ; It has all the earth fault loop paths for the various types of earthing arrangements commonly encountered.
It will be just a case of utilizing this to you situation.
 
Without doing your work for you I'd say this.
You need to know the earthing system to the building (TT, TNCS, TNS) once you find that out it's pretty straight forward, In fact the schematics for those systems are in BS7671. You just need to indicate the load and highlight the path an earth fault would take.
 
We have a Trainee Forum you might be interested in joining if you're currently on a training course or part way through an apprenticeship. It's free so have a read of this and make an application if you like.
