What is the difference between a power strip and a whole house surge protector?

A surge-protected power strip only protects devices plugged into it. A whole house surge protector is installed at the main electrical panel and protects every circuit simultaneously including HVAC, hardwired appliances, and EV chargers. Both have a role - the panel device handles large events, the strip handles daily small surges on sensitive electronics.

Where do most power surges come from in Arlington TX homes?

About 80 percent of power surge damage comes from internal surges generated by large appliances cycling inside the home - HVAC compressors, refrigerators, EV chargers. The remaining 20 percent comes from external sources like lightning and Oncor utility switching surges. A panel-mounted whole house surge protector handles both.

How do I know if my whole house surge protector is still working?

Check the indicator LED on the device. Green or 'Protected' means the device has remaining capacity. Red or no light means it was depleted by a surge and is no longer protecting your home. Check this light once a year. Call Bolt Electric at (817) 754-5700 if you need help locating it.

What joule rating do I need for a whole house surge protector in Arlington TX?

Minimum 1,000 joules for basic protection. 2,000 to 3,000 joules for most Arlington TX homes. 3,000+ joules for homes with EV chargers, home automation, or significant electronics. Higher joule ratings mean more surge absorption capacity before the device is sacrificed.

Should I install surge protection when I upgrade my electrical panel in Arlington TX?

Yes. A panel upgrade is the most efficient time to add surge protection - the panel is already open. Bolt Electric includes the surge protection option in every panel upgrade quote. It adds minimal time to the job.

Plain Language Explainer

What Is Three-Phase Power?

Standard residential and most small commercial buildings in Arlington TX run on single-phase power — 120V or 240V delivered on two hot conductors and a neutral. Three-phase power delivers electricity on three hot conductors at 208V or 480V. It is more efficient for large motors and high-draw equipment.

Three-phase is required for: large commercial HVAC systems, commercial elevators, CNC machinery, industrial compressors, commercial kitchen equipment rated for three-phase, and large commercial EV charging equipment.

What We Provide

Three-Phase Services We Provide in Arlington TX

New Three-Phase Installation

If your Arlington TX commercial space does not have three-phase service, we first confirm whether three-phase is available at the Oncor meter for your address. If available, we install the three-phase panel and distribution equipment. If not, Oncor must upgrade the transformer — a process that typically takes four to eight weeks. We coordinate the Oncor application and give you a realistic timeline before you commit to equipment purchases.

Three-Phase Panel Upgrades

Existing three-phase service that needs more capacity — adding circuits, upgrading amperage, or reconfiguring distribution for new equipment. We calculate the new load, assess whether the existing service entrance can support it, and upgrade what is needed.

Three-Phase Equipment Circuits

Dedicated three-phase circuits for specific equipment: commercial HVAC units, industrial machinery, commercial cooking equipment, compressors, and large commercial EV chargers. Each circuit is sized for the equipment nameplate amperage with appropriate wire gauge, breaker size, and conduit.

FAQ

Frequently Asked Questions

Open the main electrical panel. If you see three hot conductors coming in from the utility and three rows of breakers (rather than two), you have three-phase service. If you are not sure, call us at (817) 754-5700 — we can often help you identify the service type from a description of the panel.

The cost depends entirely on whether three-phase is available at the Oncor meter for your address. If it is, the upgrade is the cost of the three-phase panel and installation — typically $3,000 to $8,000 depending on amperage and scope. If Oncor needs to upgrade the transformer, there may be additional utility charges and the timeline extends to four to eight weeks. We confirm availability and give you the full picture at the site assessment.

Yes. Restaurant kitchen equipment — commercial ranges, ovens, fryers, and large refrigeration units — frequently requires three-phase power. We assess three-phase availability at your specific address before you commit to equipment purchases or a lease on a space that does not have three-phase service.
