Electrical panels cost about $1,100 to upgrade or replace and $1,300 to install. Generators cost about $4,000 to install and $250 to repair. Find detailed electrical work prices in the Cost Guides below.

The electrical power that courses through your home is like your house’s life blood. Ceiling fans, computer networks, lights, and perhaps even your heating and cooling rely on electricity to function. Whether you’re having electrical problems, adding outlets, upgrading a panel to accommodate a new appliance, wiring a new home

Electrician Rates

When hiring an electrician, be aware that most electricians charge a minimum fee for their visit. This even includes visits for small projects such as installing a plug or light switch. But that fee will roll into the cost of the job. In other words, although an electrician may charge $70 just to walk in the door, that money might cover their first hour of work. Hiring an electrician can be an expensive task if you’re not aware of possible hidden cost factors.

Most electricians charge by the hour, and an experienced professional should be able to give you a reasonably accurate hours-needed estimate from the start. But there are other factors that can affect the cost of your electrical job, depending on the type of job you need accomplished. The average electrician charges from $50-$100 an hour, plus additional costs for parts depending on the complexity of the project. This brings the national average cost to hire an electrician to just over $300.

Install and Repair a Home Generator

The basic cost to install a home generator varies based on the generator you choose. Home back-up generators, such as Generac brand generators, start at around $2,000 plus installation. Your electrician will be able to determine the type of generator appropriate for your household and needs. Different types of generators provide different services such as full power to your home in the event of an outage, or just partial power to keep major appliances running such as hot water and your refrigerator


Our autonomy and comfort depend a lot on the electrical system of our DIY camper van conversion. No power means no fridge, no lights, no smartphone = no Instagram = no #vanlife as we know it 😛 Therefore, we want our electrical system to be safe, reliable and to work from the first time; trial-and-error is not acceptable here.

After three years on the road full time, we’re happy to report that our system works as we planned, nice! Designing the electrical system was one of the most intimidating task of the conversion process and if you’re reading this, you are probably looking for some guidance

To mitigate these scenarios companies like Battle Born Batteries, Trojan, Relion, Victron, now include BMS (Battery Management System) built-in their batteries. The BMS is in charge of watching if parameters (temperature, voltage, current) are within safe range. For example, the BMS will prevent charging the battery if the temperature is too low; it will also regulate the amount of power you can take out of the battery. It makes using a Lithium battery safe.


That’s quite an issue for us, knowing we use our van for skiing all winter. An battery do better in that department, but still performs better around room temperature; that’s the main reason why we installed

Because we live full-time in our van, we never let the interior freeze (because food/liquid/comfort) so that solves the issue for us!

Note 1: While LiFePO4 cannot be charged below freezing temperatures, they can still be discharged. So it would be possible to install a 12V heat mat to prevent the battery from freezing…

Note 2: In fact, some brand of Lithium batteries can be charge below 32F/0°C, but at a slower rate. Check your battery specification sheet

A Comprehensive Guide for Wiring Diagram

What is a wiring diagram?

A wiring diagram is a visual representation of components and wires related to an electrical connection. This pictorial diagram shows us the physical links that are far easy to understand an electrical circuit or system. One wiring diagram can signify all the interconnections, thereby signaling the relative locations. The use of a wiring diagram is positively recognizable in manufacturing or electrical troubleshooting projects. It can prevent lots of damage that even derail an electrical plan.

Why do we use wiring diagrams?

Wiring diagrams are highly in use in circuit manufacturing or other electronic devices projects. The layout facilitates communication between electrical engineers designing electrical circuits and implementing them. The pictures are also helpful in making repairs. It shows whether the installation has been appropriately designed and implemented while confirming the safety regulators.

A wiring diagram can also be useful in auto repair and home building projects. For example, the proper location of light fixtures and electrical outlets can be easily by a home builder to avoid costly defaults or building any code violations.

Benefits of Wiring Diagrams:

Drawing a wiring diagram offers several advantages, as given below.

The diagram is easy to share even electronically.

The process of creating a diagram is fast and allows for conventional construction.

Access to hundreds and thousands of wiring symbols makes the diagram more efficient to be understood.

The diagram is simple to edit as per the different conditions.

The proper tool provides precise placement of symbols, which is an impossible task to be done by hand or other means.

Type of wiring diagram

With the use of different symbols, an electrical wiring diagram mainly consists of three main types. Everything related to an electrical system can be shown on one of the charts to ensure that interconnections are working correctly. Its three main kinds are as follows

Some Guidelines to Colour Marking

Guide to colour marking for three-phase circuits

Durable and legible markings shall be provided at the interface where the new and old versions of colour code for fixed electrical wiring exists. A warning notice shall also be displayed prominently at the appropriate distribution board that controls the circuit.

Where the existing red-coloured or yellow-coloured cable (phase conductor) is to be connected to a new brown-coloured cable (phase conductor) of the same circuit, at the interface, the existing and new circuits shall be labelled as shown below.

Where the existing blue-coloured cable (phase conductor) is to be connected to a new brown-colured cable (phase conductor) of the same circuit, at the interface, the existing blue-colured cable shall be labelled and provided with brown-coloured sleeve as shown to avoid confusion.

Warning notice at distribution boards

Where new circuits using the new colour code are to be added in existing electrical installations installed having circuits in old cable colour code, the licensed electrical worker responsible for the work will have to do the necessary colour marking on the cables and place a warning notice (see below) on the relevant distribution boards.

How Much Does It Cost to Wire a House?

Electrical wiring is the process of connecting various wires throughout a given space for the purpose of conducting electricity. This could be the rough wiring done in a new addition or building prior to connecting appliances and fixtures, or it could mean the finished wiring and addition of a new electrical circuit to a home.

Wiring projects differ in cost depending mostly on the scale of the project. Rewiring an entire home, for example, will cost far more than the new wiring involved in a home addition. Costs also vary by area, as some electricians will charge per hour while others charge by the job. On average, the cost to wire a home is around $4 per square foot. Therefore, to rewire a 2,000 square foot home, the total cost would be about $8,000.

Basic Wiring

Take a look at any panel or wiring inside a home, and you’ll likely find wires in different, distinct colors depending on the area. Black and red wires indicate a “hot” wire or the conduit for electricity. Black means a hot wire that goes to a switch or outlet. Red is a hot wire for switch legs or for connecting smoke detectors. White wires indicate a ground, or neutral, wire. Green wires and copper wires are used solely for grounding. Blue and yellow wires are hot wires pulled in a conduit. Blue is for 3- or 4-way switches and yellow is for switch legs.

Each wire is marked with its material, size, type of insulation, and, in many cases, the brand that produced it. For example, a cable with three wires inside, one being a ground wire, made of copper, measuring 12 gauge, and rated for heat resistance and 600V will be marked 12-3 to indicate the gauge and number of wires, G for ground, AU for copper, 600V for the maximum volts it can carry, and NM-B for non-metallic, heat resistant insulation.

Other codes may include:

12-2: a 12 gauge cable with 2 wires.

14-2: a 14 gauge cable with 2 wires.

14-3: a 14 gauge cable with 3 wires.

14-3G: a 14 gauge cable with 3 wires, including one ground wire.

AL: an aluminum wire.

T: thermoplastic insulation used.

H: heat resistant.

HH: high heat resistant.

W: this wire can be used in wet areas.

X: synthetic polymers are used to insulate.

N: this wire is nylon coated.
