Permits

Permits and inspections

Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.

Warranty

What's covered

Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.

05 - WHO TO HIRE

Why hiring a licensed electrician matters.

For generator interlock switch installation, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.

Keil Electric

A licensed electrician

Licensed electrician walks every job. Veteran-owned, family-run.

Permits pulled and inspections coordinated when required by the AHJ

5/10-year + lifetime warranty in writing. Parts and labor. Transfers with the home.

Fully insured + workers' comp on every crew

The price you sign is the price you pay

A handyman

Unlicensed for electrical

No state electrical license. Can do simple swaps but not panel work, rewires, or service upgrades.

No permits. Work won't pass inspection if the city audits it later.

No structured warranty. "Call me if something breaks" isn't enforceable.

If something they did causes a fire, your homeowner's insurance can deny the claim.

Cash discount may show up on the invoice.

DIY

Doing it yourself

Cheap, but only if everything goes right. Most electrical work involves load calc, code, and permitting.

A failed inspection means redoing the work. Selling the home later, the buyer's inspector flags it.

No warranty if something fails. Replacement is on you.

Live wiring is a real safety hazard. Most fatal home electrical accidents are DIY.

If you know what you're doing, fine. If you don't, call us first.

What we see for generator interlock switch installation in Wimberley

Wimberley is a Hays County Hill Country town with downtown housing (historic to mid-century), ranch acreage, and substantial second-home and short-term-rental properties. generator interlock switch installation jobs commonly include multi-structure ranch wiring, generator installs (lightning and outage exposure), older-home rewires, and seasonal-property service work.

How generator interlock switch installation typically runs in Wimberley

Generator interlock kits are the budget alternative to a transfer switch, a panel-listed mechanical interlock that prevents the main breaker and the generator backfeed breaker from being on simultaneously. Code-listed kits exist for Square D, Eaton, GE, and Siemens panels; cross-brand or generic kits are not code-compliant. Install includes the inlet receptacle (typically NEMA L14-30 or 14-50 weatherproof), the cable run to the panel, the backfeed breaker, and the interlock plate itself. Permit gets pulled and the inspector walks the install before close-out.

Permits and code in Texas

Austin metro cities pull permits through their own AHJs (the city of Austin uses Austin Energy and the city development services; outlying cities run through the county). The state adopts the National Electrical Code with Texas amendments. We pull the permit when the scope requires it, schedule any inspection, and close out the work in your file. Wimberley-specific permit notes go on the quote so you know what is required before any work begins.

Calls from this page reach the Austin team directly. Wimberley is part of our day-to-day coverage, dispatched from our Round Rock shop with the same crew that runs every other Austin-area job. After-hours emergencies are dispatched when capacity allows; routine jobs are usually scheduled within a few business days depending on parts and scope.

Common questions for Generator Interlock Switch Installation in Wimberley

How is an interlock different from a transfer switch?

A transfer switch is automatic or manual, switches between utility and generator, and is a separate piece of equipment. An interlock kit is a manual mechanical device installed at the panel that physically prevents both sources from being on at once. Interlocks are cheaper but require manual operation.

Will an interlock work with my panel?

Most modern panels (Square D QO, Eaton CH, GE THQL, Siemens) have listed interlock kits available. Older panels or unusual brands sometimes do not. We confirm compatibility before quoting.

How big a portable generator do I need?

Depends on what you want to power. A 3,600W generator runs essential refrigeration, lighting, and small loads. A 7,200W generator runs more, including a window AC or microwave. Sizing depends on what you actually need during an outage.

Is backfeeding without an interlock illegal?

Yes. Backfeeding through a "suicide cord" or any setup that does not include a listed interlock or transfer switch is a code violation and a serious safety risk to utility lineworkers. We will not do those installs.

How much does an interlock install cost?

Total cost includes the interlock kit, the backfeed breaker, the inlet receptacle, cable, and labor. We quote in writing after the panel check.
