7 Steps to Install Tesla Home Charger Outside Easily

What are the pros and cons of having your tesla home charger outside? And how to install it. We’ll see a step-by-step guide through this post.

First, You should hire a certified engineer to attach your Electric car Adapter, just like any other electric home outlet. You must carefully consider the ideal position for the charger because every installation is different.

For example, customers without a carport may place the weatherproof Tesla Wall Connector outside. The wall charging station is often fixed to the building wall when parking is next to it.

The Wall Adapter is one of the options available for you if you own a Tesla for charging. The third-generation Tesla Charging Connector, released in 2020, significantly improved the vehicle’s earlier generations.

The new adapter appears different (and stunning), but there have been considerable modifications to the inside workings.

Elon’s company advises setting up your home charging infrastructure before receiving your vehicle. Most setups only require a few hours, but it might take up to two weeks to locate and schedule an electrician.

To effectively set up rapid charging technology in your house, adhere to the following steps:

1. Hire an Electrician

To find a local installer, use your mobile app’s Search an Electrician tool and enter your zip code.

2. Ask for an Estimate

When you’ve located local electricians, get in touch with them and let them know what installations you need to be done. Now that so many electricians give estimates online and by mail, getting numerous quotes is simple.

3. Set up an Installation Date

Send your electrician a copy of the Order Shipping Confirmation email to arrange a time for installation.

Operating a car and recharging it at home will often be financially advantageous, even if these costs might increase. They will typically cover safety concerns and provide lengthy benefits (compared to refilling a petrol tank).

Tesla Home Charger Outside Installation

Operating a Tesla and recharging it at home will often be financially advantageous, even if these costs might increase. They will typically cover safety concerns and provide lengthy benefits (compared to refilling a petrol tank).

Step 1: Remove the Charger

The first step after taking the charger from the package is to detach its front cover.

Upon that wall adapter, there seem to be two covers. An internal, weatherproof cover is located within the exterior surface. Six T20 security pin Torx screws hold this lid in place. The inner covering lifts off when these screws are removed.

Step 2: Mount the Adapter

It would help if you chose a feasible solution before installation. First, ensure that the wire can reach the vehicle’s charging outlet.

Usually, this entails putting the chargers on the garage wall or parking near the car’s charging outlet. Tesla suggests a hanging height of Four feet above the floor, with at least 8 inches of room around it to enable cable hanging.

Step 3: Assemble the Conduit

It would help if you addressed several variables before choosing a conduit. The first consideration is conduit size, determined by the number of wires passing through it and the kind of conduit employed.

Four figures have been supplied to demonstrate the quantity of THHN/THWN isolated wires of different gauges that may be routed through four typical types of conduit.

Step 4: Sub Panel Connections

Before performing any electrical work on a sub-panel, turn the breakers on the main panel that supplies electricity to the sub-panel. Whether operating on a significant panel, you might not be capable of turning it off.

However, a licensed electrician will understand how to operate safely on a live panel.

The white wire is connected to the neutral crossbar, which must be grounded. The black cable represents Phase 1, while the red wire represents Phase 2. These phases connect to the two junctions of a 240V circuit breaker.

In any event, you may add a separate 50-ampere circuit for the adopter.

Step 5: Charger Connectivity

The neutral wire connects to a little metal block on the fuse box. Its two-phase wires are routed through terminating connections on the top of a vast green plastic block.

The phase wires are secured with two Phillips screws at the front of this block. Before removing the wires, make sure to release these screws completely. Then, after adjusting the screws, tug on the wires to ensure they’re secure.

Step 6: Rotary Switches

Two different DIP circuits are located within the wall charging station and are used to control the charger on how it should be wired.

For example, while you connect the adapter with two 120V phases, you may alternatively configure it with a solitary 240V phase reverting to a neutral (line to neutral).

Step 7: Closing the Charger

Before reattaching the inner cover, ensure the ribbon cable is connected to that same fuse box on the interior of the cover. The inside cover is fastened using the same T20 safety Torx screws previously removed.

Finally, the outer covering is snapped onto the power adapter by pushing along its sides. The solitary T10 Torx screws at the bottom secure this lid.

Advantage: Simplicity and dependability

A household electric vehicle station is far handier than a commercial fast adapter. With a home adapter, you will not have to wait for a charging station or attempt to locate one inside your car’s leftover range.

Benefit: Increased Property Worth

Installing a fully electric outlet in your house is a long-term commitment. However, it will not only save you money on your EV’s operational costs, but it will also increase the value of your house if you decide to sell it.

Major Downside: Potentially Long Charging Times

There are several at-home adapters on the marketplace, but not all of them will meet your requirements. If you choose a connector that fails to perform its job swiftly, you’ll have to wait a long time to recharge your EV’s batteries.

However, this disadvantage is entirely preventable if one recognizes what to look for in adapters!


The Tesla Power Adapter is a $400 residential charging alternative. However, remember to factor in EV charger installation expenses since you’ll need a reputable, qualified, and skilled electrician to guarantee your wall adapter is installed correctly.
