Will a Tesla Wall Connector Blow My Main Fuse?
To keep your main fuse from blowing, you need a smart installation that respects your home’s power limits, and that’s exactly what we do!
It’s a valid fear: plugging in a high powered Tesla shouldn't mean sitting in the dark just because your aircon kicked in. We specialise in load-balanced installs that 'talk' to your switchboard, protecting your home while keeping your car at 100%.
Whether you need a basic Tesla mobile connector, a professional wall connector, or a high speed commercial DC setup, we handle the heavy lifting.
From switchboard upgrades to seamless home installations, we make sure your charger is fast, safe, and ready for the morning rollout.

Types of Tesla EV Chargers That We Install
There are three main ways to power your Tesla, and the right choice depends on how much you drive and how fast you need to get back on the road. We don’t just "plug and play"—we assess your site's power to make sure your chosen charger actually performs at its limit.
Level 1: Tesla Mobile Connector
Look at this as your of emergency back up option. It’s slow, it’s steady, and it’ll get the job done, but you’ll be waiting all weekend for a full charge.
đ Phase: Single-Phase Only
đ The Reality: Even if you have a 3-phase outlet in your garage, the Tesla Mobile Connector is a single-phase device. It draws power from just one of those phases.
âď¸ The Setup: Plugs into a standard 10A or 15A Australian wall socket.
đ The Speed: Adds about 10–15 km of range per hour.
đ Best For: Drivers who cover less than 30–40km a day or those who have all weekend to top up. It’s a great bit of kit to keep in the boot for road trips, but most owners find it too slow for daily use.
Level 2: Professional Home & Commercial AC Chargers
This is the go to setup for most Tesla owners. Unlike a portable plug, the Gen 3 Wall Connector is hardwired directly into your switchboard, making it a permanent, high speed power source for your garage.
đ Phase: Single-Phase or Three-Phase
đ The Reality: This is the most versatile unit.
âď¸ The Setup: Hardwired on a dedicated 32A circuit. Compatible with both Single-Phase and Three-Phase power.
- Single-Phase: Delivers up to 7.4W (standard for most Sydney homes).
- Three-Phase: Delivers up to 11kW or 22kW.
đ The Speed: Adds up to 50km/hr (Single-Phase) or 75km/hr (Three-Phase).
đ Smart Features: Includes wifii for over-the-air updates, power sharing for multi car households, and dynamic load management to protect your main fuse. This is the setup that ensures you wake up to a full battery every single morning.
Level 3: Commercial DC Fast Chargers
For businesses, fleets, or rapid turnaround environments, Level 2 isn't always enough to keep the wheels turning. Level 3 chargers skip the car's internal converter and pump power directly into the battery, slashing charge times from hours to minutes.
đ Phase: Three-Phase Only
đ The Reality: These units require a massive amount of energy (starting at 25kW and going up to 350kW). They bypass the car's internal converter and pump DC power straight into the battery. You won't find these on a single-phase residential street; they require dedicated commercial 3-phase infrastructure.
âď¸ The Setup: Requires a high voltage industrial connection.
đ The Speed: Can add 270km+ of range in just 30 minutes.
đ Best For: Delivery hubs, car rental fleets, or commercial properties looking to provide a Supercharger-style experience for customers and staff.
Our Tesla EV Charger Installation Process
We’ve got our installation down to a fine art so we can get in and out without turning your house into a construction zone. We don't just show up and start drilling; we follow a specific sequence to ensure your Tesla is charging at its maximum safe speed from the second we leave.
1ď¸âŁ Digital Site Assessment
Before we touch a tool, we need to see what we’re working with. You send us a few clear photos of your switchboard and your preferred mounting spot in the garage or driveway. We’ll check your mains electrical capacity and provide a fixed price quote so there are no hidden extras on the day.
2ď¸âŁ Dedicated Circuit Installation
A Tesla Wall Connector shouldn't be spliced into an existing circuit. We run a brand new, heavy duty 32A cable directly from your switchboard to your charger. We take the time to hide conduits and keep the run as clean as possible, maintaining the premium look of your home or office.
3ď¸âŁ Commissioning & App Sync
This is the part most general electricians miss. We log into the Wall Connector’s internal wifi to configure the "Commissioning Wizard". We set the correct amperage limits, update the firmware, and sync the unit to your Tesla App. We make sure the push-to-open button on the handle is working perfectly before we pack up.
4ď¸âŁ Safety Testing & Certification
Safety isn't optional. We perform a full suite of tests, including earth-loop impedance and RCD trip times, to ensure the system is bulletproof. Finally, we issue your mandatory Certificate of Electrical Safety (CES), which is essential for your home insurance and Tesla’s hardware warranty.
Home Tesla Electric Vehicle Charger Installations
Most Tesla owners start with a standard wall plug, but they quickly get tired of the trickle charge that takes all weekend to fill the battery. We specialise in permanent home Tesla EV installs that take you from emergency backup speeds to a full battery every single morning.
Our residential service is focused on a clean finish; we hide conduits where possible to keep your garage looking premium. We don't just bolt it to the wall; we assess yourhome's total power load to ensure your car, aircon, and oven can all run at once without tripping your main switch.
Commercial Tesla Electric Vehicle Charger Installations
For offices and retail sites, it’s not just about installing a socket, it’s about ensuring your building can handle the extra load. We design commercial Tesla setups that let your team or customers charge up without knocking out the power to the rest of the office.
Whether you need a single bay for the boss or a multi unit Supercharger setup for a fleet, we handle the heavy lifting.
We specialise in dynamic power sharing, allowing multiple Wall Connectors to run on a single circuit, and we provide all the documentation required for Strata or facility management approvals.
Do I Need a Switchboard Upgrade for a Tesla Charger Install?
Not always, but it’s a common question. Most modern Australian homes can handle a 32A Tesla Wall Connector without much drama.
However, if your switchboard is 30+ years old, still uses ceramic fuses, or is already maxed out by your aircon and oven, a upgrade might be necessary for safety.
During our digitalsite assessment, we check your main fuse capacity. If your board is reaching its limit, we don't just tell you no, we offer two solutions:
⥠Dynamic Load Management: We install a sensor that "talks" to your charger, slowing it down when the oven is on so you don't trip the main switch.
⥠Switchboard Modernisation: We bring your board up to 2026 standards with modern RCDs and circuit breakers to handle the new demand safely.
