EstiMaker PalmOS 1.1a

This free electrical estimating software provides assistance to electrical professionals with the estimating/bidding process. By using this free electrical estimating software an estimator get the ability to perform a take-off estimate in at least a third of the usual time. The software contains database of over 4600 electrical parts along with pricing and labor data for each part. In order to compute all the factors and create a job estimate, just choose the parts needed for a job. Then point out the quantity of each part and enter amount for extras like special equipment and rentals. The software can create limitless number of jobs to be kept for future reference.

Electrc 2005

This free electrical estimating software is ideal for electrical contractors, engineers, inspectors, estimators, and electrical maintenance personnel. The software execute wire sizing, conduit fill, motor, lighting, panel schedule, transformer, voltage drop, box fill, fault current, and power factor correction calculations. The free electrical estimating software also has built-in reference table from the NEC. Many NEC parameters are supported as well as parallel conductors per phase, ambient temperature derating, terminal temperature derating, quantity of current carrying conductors derating, circuit type, voltage drop percentage, and more. All files are saved to disk and reloaded for future application.

Resistor Values

This free electrical estimating software can work out the value of a 4 band resistor based on the color bands or the reverse. It can demonstrate the color bands of a resistance value entered by the user. The trial version is limited to resistance values of 1000 Ohms (1 KOhm) or less whereas the registered version shows resistor values up to 99000000 Ohms or 99 MOhms.
