V1.001.21 corrected the insulation temperature of the wire to 90 degrees, and the correction coefficient during the period of 40 degrees per week was changed from 0.96 to 0.95.
V1.001.20 announced on 2020-02-11 [User Electrical Equipment Installation Rules] updated and revised,
Corresponding corrections to the ampere value of various cables.
V1.001.19 takes 60 degrees at the wire insulation temperature,
When PEX cable is used for wiring, when PVC pipe is used for piping, the ampere value of the wire will refer to the PVC wire
[Insulation temperature 60 degrees] Ampere value review of the configuration;
In addition, when the PEX cable is used for the wiring, the ampere value of the wire will refer to the PEX line when the metal tube is used for the piping
[Insulation temperature 60 degrees] Ampere value review of the configuration.
V1.001.18 increases the calculated capacity of the transformer to 250KVA.
V1.001.17 The thick steel conduit (RSG) produced by most factories does not produce G92 pipe diameter. It is recommended to replace it with G104 pipe diameter.
V1.001.13 Because the mains voltage drop may be composed of multiple branch mains (panel or transformer... etc.), the single-stage 2% voltage drop recommendation is cancelled
Display of length.
V1.001.12 adds transformer equipment category, and can calculate transformer primary and secondary side protection switch and distribution pipeline diameter
(According to Article 177 of the House Wiring Installation Rules).
-------------
V1.001.9 adds:
A. For 110-volt appliances, the motor is 1 horsepower, and the others are limited to 5 kW. 220 volt appliance, electric motor with 3 horsepower,
Others are limited to 30 瓩. But without three-phase power supply or other special reasons (such as window-type air conditioners), 110 volt motors must be discharged
As wide as 2 horsepower, the 220-volt motor has to be relaxed to 5 horsepower.
B. Add a reminder when calculating the 3-phase 380V branch circuit (if it is a complete set of equipment and contains single-phase equipment, the N-phase wire diameter needs to be
Adopted according to 3-phase specifications.
C. The main switch primary side pipeline and secondary side copper inspection selection increase source is the connection line and the voltage device options and added
3-phase 4-wire 110-190V field. The grounding wire is corrected according to the above phase selection.
D. It is recommended to use Y-Δ step-down starter for those who increase the horsepower of 3 phase 220V up to 15HP and 3 phase 380V horsepower up to 50HP.
E. When choosing the household connection line or transformer, add the judgment 3-phase 220V and the capacity of the meter device must be below 99KW.
The capacity of the meter device of the 3-phase 4-wire 380V must be below 499KW.
-----------------------------------
V1.001.8 adds:
When the shunt rating of the distribution box is less than 30A, the main overcurrent protector should not exceed 200A.
---------------------------------

This system contains two major categories:
1. Calculation of the branch pipeline in the panel: according to different equipment types, voltage, wire insulation temperature, ambient temperature, and pipeline material...
Calculate suitable NFB and pipeline diameter for installation.

2. Main switch primary side pipeline and secondary side copper inspection selection: according to the capacity of the main switch NFB, provide the primary side distribution pipeline diameter and secondary side
Specification of secondary side copper bar.

Congratulations, you found it!
Mechanical and electrical (hydropower) engineering tools.
Such a tool can satisfy your query and calculate the NFB (number of poles-AT/AF) of various electrical loads and a practical small tool for suitable distribution pipeline diameter.

-4.2MB installed space, is a practical tool, super space saving.

Function application

►This system provides the maximum distance (MAX) that the pipeline of the circuit can be equipped with in the load calculation when the shunt pressure drop is less than 3%, so as to avoid the pressure drop >3% caused by the installation length. And violate the regulations.

►[Main switch primary side pipeline check and selection] The recommended length L of the trunk line is calculated and displayed based on the pressure drop of 2%.

►The ambient temperature of the wire configuration will affect the ampere capacity of the wire; therefore, this system specially incorporates this factor into the calculation; please pay special attention to the ambient temperature of the wire configuration during the review; include it in the review, and have obtained the appropriate Wire distribution.
