Analyzing and Resolving a Tesla Model Y Owner’s Home Charging Issues 2024

When Dylan, who owns a Tesla Model Y, asked for help in a Facebook group I run, I saw it as a chance to talk about keeping Home Charging Issues I messaged Dylan and suggested making a video of me finding and fixing the problems. He said yes. I planned to do it within 10 days.

Afterward, I contacted Qmerit, the company that supports my YouTube Channel, State Of Charge, and asked them to reach out to one of their electrical workers in San Antonio, Texas. I requested them to set up the fixing for Dylan’s system as soon as they could. Qmerit not only said yes but also offered to pay for the whole repair, which I was really thankful for. We scheduled the fix for February 12th, only nine days after Dylan asked for help on Facebook.

Unexpected Challenges in Tesla Wall Connector Installation

On the morning of the 12th, I flew to San Antonio and met with Matt Trout from Qmerit at the airport. Matt came specifically to discuss the importance of hiring an EV charging equipment expert when installing a home charger, and to ensure Dylan’s satisfaction with the work. We then traveled to Dylan’s house and began examining the electrical circuit that powers the Tesla Wall Connector.

At Dylan’s house, we were joined by the local Qmerit electrical contractor, Charge Pro, tasked with the repairs. Matt, Ben from Charge Pro, and I were surprised to discover not just one, but a series of issues that had caused three separate failures in Dylan’s relatively new home, which is only two years old.

We found three main problems. First, the circuit breaker for the Tesla Wall Connector had been replaced a few months ago because it failed. It showed signs of overheating, and the part where it connected to the service panel was badly burned. Dylan explained that when the breaker failed previously, a local electrician replaced it without telling Dylan that the part where it connected was damaged, as well as the breaker on the other side of the Wall Connector breaker.

Addressing Wiring Issues in Tesla Wall Connector Installation

The next issue was with the wiring from the panel, which used #6 aluminum wire and wrapped around 80 feet of the house to a junction box behind it. Apparently, the previous owner had used this for another purpose, Home Charging Issues maybe an outdoor hot tub. When Dylan bought the house and needed to install the Wall Connector, the electrician he hired used this circuit to extend another 60 feet to the garage on the opposite side of the house.

While copper wire was used for this extension, the circuit now had 80 feet of aluminum wire connected to 60 feet of copper wire leading to a disconnect box in the garage next to the Wall Connector. Dylan told us that the connection in the junction box had failed a few months ago, and another electrician repaired it without addressing the underlying issue.

We were surprised to find not just one, but a series of problems causing three different failures at Dylan’s relatively new house, which is only two years old.

Both Ben and Matt agreed they needed to get rid Home Charging Issues of the 80-foot aluminum wire in the Wall Connector’s circuit. The best solution was to install a completely new connection straight to the garage, rather than running 140 feet of wire around the entire house. They decided to run the wire up from the service panel, through the attic, and back down to the charger, cutting the length of the run by more than half.

Successful Resolution of EV Home Charging Issues

Then, we connected the Wall Connector directly to the new feed. Since the circuit wasn’t over 60 amps, a service disconnect wasn’t required by code. Dylan also preferred not to have it, as it would disrupt the style of his garage setup.

After a full day’s work, Dylan’s Model Y was charging in his garage. And yes, I managed to solve his problem in less than ten days (barely, because this was day 9!), just as I had hoped.

This shows why electric vehicle charging equipment needs special care. Dylan’s Wall Connector circuit was set up by a licensed electrician, following all rules and checks.

The Home Charging Issues arises because EV charging puts more strain on electrical parts than typical home devices. For example, NEMA 14-50 outlets, which work well for appliances like electric ranges and dryers, often fail when used for EV charging. EVs draw maximum current for long periods, straining disconnect boxes, outlets, and circuit breakers beyond their limits, leading to melting and failure.

To avoid Home Charging Issues, it’s important to hire experienced electricians for EV charging installations. They use better equipment, ensure proper connections, and avoid using aluminum wire, which can cause connection issues.
