How does PreFab streamline rough install?
PreFab Home Wiring is a new, innovative solution for completing the rough electrical install on new home builds.
- It is all your 15 and 20A non-dedicated rough install wiring in a complete plug and play package. It comes shipped on a pallet for the complete build.
- Every outlet, switch and fixture in the entire build is broken into individual harnesses for each room. Each leg of the harness is labeled, color-coded, cut and stripped to the proper length.
- A detailed and easy-to-read installation diagram is included in English and Spanish.
- The whole home solution is built and tested offsite, then shipped from our ISO certified manufacturing facility in El Paso, TX.
-
Who is the PreFab Home Wiring™ Solution for?
The PreFab Home Wiring™ Solution is ideal for Builders and Electrical Installers of new homes, apartments and condos, and townhomes.
-
How is the PreFab Home Wiring™ Solution different than a conventional rough electrical install?
Traditional wiring requires electricians to pull, cut, and connect wires on-site, which can be time-consuming and labor-intensive. PreFab Home Wiring™ arrives pre-configured, so installers simply mount, route, and complete final hookups.
With PreFab, you send us the model plans, and we provide you with a takeoff estimate on the PreFab Home Wiring Solution for you. Next, we take those plans and convert them to a custom PreFab Home Wiring™ Solution.
-
Will the PreFab solution save us money and how much?
The PreFab solution provides cumulative cost reductions through efficiency gains in the process that stretch across many areas of the project, from back-office support, material holding costs, labor reduction for rough and trim, and elimination of re-work. Each project results will differ, but we have seen efficiency gains of up to 30% reached in the Japanese market.
-
Does this product require UL certification?
All individual components—including junction boxes and wiring—are UL-certified. However, the fully assembled system does not require separate UL certification since it uses code-compliant, pre-approved materials.
-
Is there a warranty?
