Generator Transfer Switches in Pottstown: Safe Options and What to Avoid

If you live in Pottstown or the surrounding areas you may wonder “Can I install my own portable generator with a backfeed cord?” Well, the short answer is you shouldn’t. It may seem like a quick fix during an outage however, backfeeding is very dangerous not only for your family but for others along the power grid. And it is often illegal. When backfeeding you can get into serious trouble with local code enforcement and utility providers.  

This article lays out what you need to know if you live in Allentown or the surrounding areas and want to connect a portable generator safely. It includes what you need to know about generator transfer switches, interlock kits, and National Electrical Code (NEC) requirements. And how to avoid common safety mistakes. 

Why Backfeeding Is Dangerous and Illegal

Backfeeding takes place when someone connects a generator directly to a home’s wiring supply by plugging it into the outlet. This action sends power backward through the electrical system, re-energizes circuits, and can even re-energize utility lines without proper insulation. 

Here’s why that’s a big problem:

• Backfeed can electrocute utility workers. When the power goes out, line crews assume the wires are dead. Backfeeding your home without isolation can send power into those lines, putting lives at risk.
• It can destroy your appliances. Backfed power can surge through sensitive electronics and damage them permanently.
• It violates code. The NCE requires safe, listed equipment that isolates the generator from the grid. Backfeeding does not meet that standard.
• You could be held liable. If your setup causes injury or damages property, you’re likely on the hook both legally and financially.

Bottom line: Backfeeding is never a safe or legal solution. There are much better options that protect you, your home, and your community.

The Right Way: Generator Transfer Switches and Interlock Kits

To safely connect a portable or standby generator to your home’s electrical system, you need equipment that isolates the generator from the utility lines. In Pennsylvania, including Pottstown and surrounding towns, there are two main code-compliant options:

1. Manual Transfer Switch

A manual transfer switch is a device that lets you manually shift power from the utility to your generator. It’s installed next to your electrical panel and wired to specific circuits you want to back up during an outage.

Why it’s safe:

• Fully isolates the generator from utility power
• Lets you control which circuits receive backup power
• Meets NEC requirements and passes inspection

Best for: Portable generators and homeowners who want a clean and code-approved setup with flexibility.

2. Interlock Kit (UL-Listed)

If your panel supports it, an interlock kit is a cost-effective and safe way to connect a generator. It’s a mechanical device that physically prevents your main breaker and generator breaker from being on at the same time.

Important Note:
Not all interlocks are created equal. To be code-compliant in Pennsylvania, you need a UL-listed interlock kit that meets all NEC safety standards.

Why it’s safe:

• Prevents power from backfeeding into the grid
• Typically more affordable than a full transfer switch
• Works with your existing panel (if compatible)

Best for: Homeowners with a compatible breaker panel who want a safe but budget-conscious solution.

NEC Requirements and Inspections in Pennsylvania

If you’re connecting a generator to your home in Pottstown or anywhere in Pennsylvania, here’s what inspectors and utility companies typically require:

• No backfeeding. Ever. Any setup that allows utility and generator power to mix is a red flag.
• Proper isolation equipment. NEC Article 702 mandates that standby systems must prevent unintended interconnection with the utility grid.
• Listed equipment only. All switches, interlocks, and related hardware must be UL-listed or recognized by the authority having jurisdiction (AHJ).
• Permits are required. Most municipalities require an electrical permit and inspection for generator hookups.
• Proper labeling. Panels must be clearly labeled to identify generator connections and ensure safe operation.
  

Don’t guess, work with an electrician who understands NEC requirements and what local inspectors expect.

Utility Safety Reminders for Portable Generators

Whether you’re using a full-home standby unit or a portable generator with a manual setup, keep these safety basics in mind:

• Never run a generator indoors or in enclosed spaces. Carbon monoxide can kill within minutes. Always place it outside, away from windows or doors.
• Use a dedicated inlet box, not an outlet. A proper generator inlet box (wired by a licensed electrician) ensures safe power entry.
• Only use heavy-duty, outdoor-rated cords. Undersized or indoor cords can overheat and cause fires.
• Don’t overload your generator. Know what it can safely power, and stick to it.
• Schedule routine checks. Like any equipment, your generator system needs occasional testing and maintenance.
