What is an electrical switchboard?
An electrical switchboard is a component that distributes power from outside into the rest of the home. It directs current to every circuit and appliance in the home. A safety switch or RCD is installed for safety. Its goal is to shut off the electricity supply to the building when there is a change in electrical current.
Electrical or power switchboards are vital in a home as their key goal is to distribute electricity across a home. There are many reasons why you might need a switchboard upgrade, with the following being the most common ones:
- Flickering lights
- Short-circuiting appliances
- Overheating cables
- Too many appliances
- Electrical defect notice
Why do you need a switchboard upgrade?
There are many reasons why switchboard upgrades are compulsory, with the following being some of the reasons:
- You want to install new electrical points
- The current switchboard is old, and older systems are more likely to create issues
- The fuse box contains ceramic fuses, making it old or outdated
- The circuit breakers continually trip
- Lights within the building randomly flicker
- Odd or buzzing sounds coming from the electrical switchboard
All of these reasons and the rise in electrical demand from appliances have resulted in older switchboards being unable to manage the load. An electric shock, electrical fire and many other dangerous outcomes can happen when older electrical switchboards overload.
Electrical switchboard upgrade cost
There are many costs associated with an electrical switchboard upgrade since you need to consider many factors. The age of the property, property type and location are some of the factors to consider. An electrical switchboard upgrade can cost anything from $650 to $5,000. However, the final price will depend on the building’s current switchboard age and wiring system.
Here is a breakdown of the average cost:
- A general upgrade can cost anything from $800 to $2,000
- If the building’s electrical wiring needs upgrading, this could add another $2,000 to $4,000 to the price, especially if the switchboard needs to be moved
- You can expect to pay $3,000 to $4,800 for a three-phase switchboard upgrade
You should note that the prices above are estimates, and they might differ depending on the electrician carrying out the upgrade.
Is a switchboard the same as a distribution board?
