Electrical Panel Upgrades for EV Charging in Allen, TX
Service capacity work for homes along SH-5 and the older Allen blocks where the load calculation says no before the charger can say yes.
When the Panel Has to Change Before the Charger Can Go In
Electrical panel upgrades for EV charging in Allen come up more often than new homeowners expect, and almost always for the same reason. A house on a 100 or 125-amp service with central air, an electric range, a dryer and a water heater is already close to its calculated limit, and a 48-amp continuous charging load is not a rounding error. Allen EV Charger Installation runs the load calculation first and tells you plainly which of three paths you are on: there is room and we proceed, there is nearly room and a load-management device solves it for less money, or the service genuinely needs upgrading to 200 amps. We see this most in the established neighborhoods closer to Main Street and SH-5, and in homes where a previous owner added circuits without ever revisiting the service size. A panel upgrade is a bigger job than a charger install, it involves coordination with Oncor, and it is the kind of work where an unlicensed shortcut is genuinely dangerous. Everything here runs on permit under our TDLR contractor license.
What a Service and Panel Upgrade Covers
Full load calculation on the existing service.
Connected load totalled against the current rating, with the arithmetic shown to you, so the upgrade is justified by numbers rather than asserted by a salesperson.
The honest alternative, offered first.
If a load-management device or a lower-amperage charger circuit will solve your problem for a fraction of an upgrade, we say so. Not every tight panel needs a new service.
New 200-amp load center and main breaker.
Modern bus, correct breaker compatibility, and enough spaces left over that the next addition is not another upgrade.
Service entrance conductors, meter base and mast as required.
The portions that actually have to be replaced for a 200-amp service are identified during the assessment and quoted individually rather than assumed.
Oncor coordination and the disconnect scheduling.
Utility coordination for the service change, including the temporary outage window, is handled by us and communicated to you in advance so you can plan around it.
Grounding and bonding brought to current code.
Older Allen homes frequently have grounding arrangements that were acceptable decades ago and are not now. The upgrade is the right time to correct it.
Every existing circuit transferred, tested and labeled.
Each branch circuit is landed on the new panel, verified live, and recorded in a legible directory, so nothing is left as an unidentified mystery breaker.
The EV charger circuit landed on the new service.
The whole point of the upgrade is the charger, so the dedicated circuit is installed as part of the same job and the same permit.
Surge protection offered as a priced option.
Whole-home surge protection is cheap at the moment the panel is open and expensive to retrofit later. It appears as a line item you can decline.
Permit, inspection and documentation.
Filed with City of Allen Building Inspections under our TDLR license, inspector met on site, signed-off card and written workmanship warranty delivered to you.
How a Panel Upgrade Runs
- 01
The calculation that decides everything.
A licensed electrician opens the panel, inventories the connected load, measures the service entrance, and runs the calculation. You find out whether you actually need an upgrade, and if you do, you get a flat written quote separating the service work from the charger work so you can see what each costs. This visit is free and carries no obligation.
- 02
Permit and utility scheduling.
We file the electrical permit and coordinate the service change with Oncor, which is the step that sets the date. You will know the planned outage window well before the day. Materials are ordered against the specific scope rather than a generic kit.
- 03
Changeover day and inspection.
Power is dropped for the planned window, the new load center goes in, every circuit is transferred and tested, the charger circuit is landed, and power is restored. Expect this to occupy most of a day, sometimes with a utility step the following morning. The city inspection follows and we meet the inspector.
Why This Job Especially Should Go to a Licensed Contractor
We quote the alternative before we quote the upgrade.
A panel upgrade is the most expensive thing on this site, which is exactly why the cheaper honest option gets presented first. Several Allen customers a month leave the assessment with a load-management solution instead of a service change.
Service and charger are priced as separate line items.
You should be able to see what the capacity work costs and what the charging circuit costs independently, because they are two different decisions. Bundling them into one figure hides which one is driving the price.
Utility coordination and inspection are our problem, not yours.
The Oncor scheduling, the permit, the inspector appointment and the signed-off card are all handled end to end. You schedule one day away from the house and nothing else.
