CableCalc BS7671 - 17th Edition

You may be aware that the 17th Edition of the wiring regulations (BS7671:2008) are due for release this month and may be used as from January 2008.

After 1st July 2008 all installations must be designed, installed, inspected, tested and certified to meet the requirements of BS7671:2008

The main changes of the regulations affecting electrical installation design are:

Appendix 4 'Current-carrying capacity and voltage drop cables and flexible cords'.

Chapter 41 'Protection against electric shock', disconnection times and maximum earth fault loop impedance values for protective devices.

CableCalc has been completely re-written specifically to incorporate the above changes, using the latest software tools available to provide a new look. It now includes many new schedules and improved reports, as well as being fully compatible with Windows XP and Windows Vista.
