Electrical Wiring Tips for Home Electrical Wiring Projects - Vol 1
Optimal Efficiency
Inverters are now available with a real efficiency of up to 97.1%. The system efficiency is crucial for maximum power output and accomplished when selecting high quality system components.
Surge Voltage Protection
Inverters should be equipped with thermally monitored varistors on the DC side and is indicated with a LED and have the ability to be supervised with a remote monitoring system.
Reliability
Highest reliability and a lifetime of over 20 years are major aspects taken into account during the design of a quality inverter. The newer inverters should come with a 10 year warranty.
Things to consider when selecting an Inverter
Simplest Installation DC distribution cases and connection boxes are no longer necessary resulting in reduced installation costs.
Connect It Anywhere The inverter can be connected to any available part of the AC distribution system of the house, and in some cases in an attic or a similar room, depending upon your application and system requirement.
Mount It Anywhere The cases should be NEMA 3R rated, weather resistant and a wide temperature range tolerance enabling the inverter to be mounted nearly anywhere. The inverter should be capable of installation directly on PV modules, on the roof or on the wall of your house. A world-wide usage of the inverter is therefore possible.
Diagnosis And Communication Communicate with your inverter is important. Measurement values and messages should be capable of being transmitted to a PC via wireless or RS485 cable where you can be continuously informed about the situation of your alternative power plant with the option to view statistics of your solar system on the Internet.

All home electrical wiring projects should be performed correctly by trained and qualified individuals who understand the principles of electrical circuit wiring and the basic fundamentals of home construction.
Detailed information is provided throughout areas of this website about the complexity of specific projects to help assist with you to understand the scope of work involved.
The following categories will provide more specific information for each project - below is an Example:
Electrical Project Skill Level:
Intermediate to Advanced - Best performed by a Licensed Electrical Contractor.
Electrical Tools Required:
Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time:
Depends on the personal level experience, ability to work with tools, install electrical circuit wiring, and the available access to the project area.
Electrical Safety:
Identify the electrical circuits found in the project area, turn them OFF and Tag them with a Note before working with the electrical wiring.
Home Electrical Parts and Materials:
Electrical parts and materials should be approved for the specific project and compliant with local and national electrical codes.
Electrical Codes and Inspections:
Installing additional home electrical wiring should be done according to local and national electrical codes with a permit and be inspected.
This is a testing tool that is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets
Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency
Lights indicate if wiring is correct and indicator light chart is included
Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.
A wire stripping tool used to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
