Windows based PC software to Calculate Copper Electrical
 Cable Sizes up to 150mm²
 to BS7671 2008 17th Edition regulations including
the 1st amendment 2011

This is a Windows based software package to Calculate Electrical Cable Sizes up to
150mm² which comply with Appendix 4 of BS7671 2008, 1st Amendment 2011
(this is a computer program and not a spreadsheet)

Suitable for either 110v, 230v or 400v ac supply voltages,
Select from a wide range of protective devices:

BS88   fuses  from  6 amp to 500 amp
BS1361  fuses  from  5 amp to 100 amp
BS3036  fuses  from  5 amp to 100 amp
MCB  (BS EN 60898) from 6 amp to 125 amp  (Types B, C and D)
RCBO      from   6 amp to 125 amp
BS1362  fuses  13 amp
MCCB  (MEM F-Frame)  from   50 amp to 250 amp
MCCB  (Square D SFA -SKA )  from   16 amp to 250 amp
MCCB  (Merlin Gerin NS160)  from   80 amp to 160 amp
MCCB  (Crabtree G-Frame)  from   40 amp to 160 amp

For the following cable types,

Suitable for TNCS, TNS and TT systems,

Apply any Grouping factors, Thermal factors, Buried factors or Ambient temperature.

Choose the cable installation methods as found in the regs book.

The software will CALCULATE VOLT DROP -
(up to 3% MAX FOR LIGHTING CIRCUITS, 5% MAX FOR OTHER CIRCUITS, OR any Value you select up to the Maximum), the software will automatically select a larger cable cable to satisfy the maximum permited voltdrop.


Calculates R1+R2 Values and ZS Values

Calculates R1+R2 and ZS Values for SWA Cable using the ARMOUR as the CPC

Shows Max permissible Value of Earth Fault Loop Impedance (Zs) for selected device's disconnection times -  0.4 seconds and 5 seconds.

OR 80% Values of MAX Earth Fault Loop Impedance (Zs) for selected device's disconnection times -  0.4 seconds and 5 seconds.

Software then Checks the calculated circuit against these disconnection times.

 

Shows the minimum Earth CPC size for the calculated cable size

NEW - Ring main design Calculations:  max length ,  Zs  and
 Basic actual cable size Calculations


ALSO Temporary safety signs to print out,
work safely - select and print various safety signs, (Licenced users only)
just print and laminate, I will add more if enough people find it useful.


Print out Calculations (Licenced users only)
Save Calculations as a text file for use in reports etc (Licenced users only)
Regulations are also quoted where possible on print out.
Great as a learning aid, or for use in projects

This software will also:

Calculate conduit sizes,
Calculate Trunking sizes,
Find maximum clipping distances,
Calculate the minimum cable bend radius,
Calculate conduit and trunking support distances,
Calculate Diversity,

This is a 100% genuine piece of computer software
written by Electricians for Electricians
