Developed by Allan Goodger Moss Vale TAFE From Boards originally developed by Ken Postill Ultimo TAFE

Ken’s Board Faults introduced by 3 x 9 Gang switches Contacts oxidise, and as a result a high resistance is introduced into the circuit Limited number of faults can be introduced into the circuit Very good at developing fault finding techniques in students in realistic scenario  Next

Allan’s Board Faults introduced by Separate Fault Card Plugged into a socket All circuit conductors from every circuit can be modified All conductors are cut at this set of sockets  Next

Board Contains Power Circuit Mixed Circuit Light Circuit Hot Water & Range Circuit  Next

Hot Water & Range Circuit Circuit to load is as per all other circuits Terminates with flying leads Load characteristics can be modified by the fault card  Next

Fault Socket B&R Enclosure PJ x 3mm groves are routered into the box lid Socket PCB is inserted into slots from the back of the lid Clamped into position by an insulated metal plate  Next

Fault Socket B&R Enclosure PJ Lid Vero Board Jaycar Part N o HP 9544 Socket Strips Farnell Part N o Cardboard acting as insulation 3mm Mild steel with 3/16” threads cut into each corner 3/16” Screws Installed from the front of the lid  Next

Socket Pin-Outs Range Load Spare Range HWS Light Power 2 Power 1 Pins Pin 16 Pins Pins Pins 7-9 Pins 4-6 Pins 1-3 From Switchboard From Loads HWS Load Range HWS Light Power 2 Power 1 Pin Pins Pins Pins 7-9 Pins 4-6 Pins 1-3 Only Half of the socket is used This allows the fault card to be spun around and a second set of faults can be introduced  Next

CB Enclosure Load side of CBs are easily accessible By using a 4mm 2 (yellow) crimp lug and crimping a 2.6mm Brass welding rod in it  Next

CB Enclosure Neutrals are easily removed By the use of turned plugs  Next Cable should be min of 50 strand for flexibility

Improvements Add/incorporate a handle into board  Next

Improvements Add/incorporate a handle into board Add spacers in-between clamping plate and back of lid The front of the lid between the screws tends to bow outward  Next

Improvements Add/incorporate a handle into board Add spacers in-between clamping plate and back of lid Pass the socket connecting wires through PCB before soldering Solder  Next
