Who is the Technical adviser on the show so far as 'Daves electrical work is concerned?!!!!!!!!! THIS NEEDS ATTENTION

1. Don't use Orange Electrical PVC conduit unless they're laying   unarmoured or unscreened cable undergound, the normal conduit would be plain grey conduit.

2. What is with the different coloured  outter sheathed electrical cable?!!!, it might look pretty , but unless you can pass off that part of the  install as communication cable work,  the actual cable this guy will be running is mainly plain white sheathed, 2C+ E flat TPS-different sizes for different applications ie for power and lighting.

The other  cables will be round black sheath cables either multicore control or TPS power cables, XLPE or NS (neutral screen )power cables.

3. Try and get these guys to mount  up ladder rack and cable tray, even a control or switch board. ....oh and if you want to try and be REALLY authentic PLEASE supply them with proper Electrician tool belt, complete with proper side cutters, pliers and screw drivers( and Fluke T6 multimeter)!!!!!!!!!!!!!!!!!!!!!
