Quick Reference Implementation for the main calculations requested by the Low Voltage Electrotechnical Regulations.

Useful tool for surveyors, engineers or electricians.

Designed for the calculation of:

* The minimum wire UNE 20460-5-523 Nov.2004, applying or not applying correction factors or by a certain voltage drop.

* The maximum cable UNE 20460-5-523 Nov.2004, applying or not applying correction factors or by a certain voltage drop.

* The automatic switch current (A).

* The voltage drop (% V).

* Maximum Allowable Power installation by installed capacity, the value of the switch or through the line section.

* The short-circuit with two options. In the case of a client in medium voltage (transformer data known) or the customer if low voltage (short circuit worst approach).

* The value of the earth resistance or the number of electrodes necessary to obtain a definite value of earth resistance.

* Corrects the power factor and reduce reactive consumption in the electric bill. Notes the benefits of this measure.
