Electrician in Mansfield, TX

The bulk of Mansfield's older housing went up between 1970 and 2000, often with 100A to 150A panels. We run a load calculation before recommending anything; when a 100A-to-200A replacement is the answer it typically runs $2,200–$4,800, quoted after assessment. Oncor or United, whichever serves the address, disconnects and releases the meter.

The two utilities in Mansfield do not have the same rules. United wants the main disconnect on the load side of the meter base, and for solar or other generation it requires a visible, lockable, lever-grip disconnect whose position can be seen without opening a door, and says breakers do not qualify. Oncor reserves the meter socket for its own equipment. We check which one you have before quoting.

We install, repair and maintain all major standby generator brands, and are the installer of record for UTS ElectricPros, the authorized Cummins dealer. On United service, United asks to be notified before a generator is connected and requires NEC-compliant transfer equipment installed by a licensed electrician; on Oncor, the transfer switch goes on the load side of the meter base. A 20kW unit installed typically runs $13,500–$17,000. Estimate only. Every installation is different; a site visit is required to determine whether your installation will cost less or more than this estimate. A licensed plumber runs the gas line, and you may hire your own.

Mansfield's Building Safety Department, at 1200 E. Broad St., requires a permit for the alteration or repair of a building system, electrical included. Single-trade electrical permits are submitted online through the city's MyGov system, and Mansfield asks electrical contractors to register with the city, providing their state license. Registration, the permit and the inspection are the contractor's paperwork, not yours.

Level 2 charger circuits for newer homes in South Pointe, Somerset and across the city, sized against the existing panel with a load calculation rather than assumed. Tesla Wall Connector and J1772.

A UL 1449-listed surge protective device at the service entrance, typically $350–$850 for a standard installation. Worth doing before storm season rather than after it.

Mansfield had fewer than 4,000 residents until about 1970, so pre-1970 homes are a small share of the city, mostly around the historic downtown. They are the ones most likely to have undersized services, ungrounded receptacles or a Federal Pacific panel, and an inspection is the right first step.

Manufacturing, distribution and retail are all part of Mansfield's economy, along US 287 and SH 360; the city broke ground in 2024 on a new manufacturing plant and headquarters near Heritage Parkway and US 287. We handle tenant finish-out, service and capacity upgrades, warehouse lighting and machine wiring, priced from drawings or a site walk with a written scope.

Mansfield had 1,375 residents in 1960 and 3,658 in 1970, so homes from this era are few and mostly near the historic downtown. Expect undersized services and ungrounded receptacles, and it is worth ruling out a Federal Pacific panel.

The city grew to 8,102 people by 1980 and 15,607 by 1990. Early-1970s homes fall inside the aluminum branch-wiring window and are worth checking, but most of this stock came later, typically with 100A to 150A panels that modern air conditioning, pools and EVs have caught up with.

Mansfield reached 28,031 people in 2000 and has grown steeply since, in communities like South Pointe and Somerset. Newer homes generally start at 200A; the work is EV chargers, generators, surge protection and solar, where Oncor's and United's interconnection rules differ.

Electrical permits for work in Mansfield are issued by the city, and it is the city that inspects the finished work. Requirements, fees and inspection scheduling differ from one DFW city to the next.

Clements Electric pulls the permit and schedules the inspection as part of the job. Texas Electrical Contractor TECL #40628.

Most Mansfield addresses are served by Oncor Electric Delivery. Part of the city is served by United Cooperative Services instead — utility territory does not follow city limits.

This matters on a service or panel upgrade: the utility named on your electric bill is the one that has to disconnect and then release the meter before the new service can be energized. Worth checking your bill before scheduling, and we coordinate that call either way.
