SIEMENS Arc Fault Circuit Breakers Editorial Review

**** The dual function 20 amp circuit breakers have garnered a positive reception from customers, who appreciate their effective protection against both arc faults and ground faults. Many users have found the installation process to be straightforward, allowing for an upgraded safety measure in their homes without significant hassle. The combination of both Arc Flash and Ground Fault protection in a single breaker has been highlighted as a notable advantage. Users reported that replacing standard breakers and outdated GFCI outlets with these dual-purpose breakers not only enhances safety but also contributes to a sleeker aesthetic, eliminating the need for unsightly GFCI outlets, especially commonly used in kitchens and bathrooms. Customers have expressed satisfaction with their decision to install these breakers, as they cater to both functionality and a more appealing appearance. However, there have been some mentions of false tripping, especially with certain power tools, and a few users encountered installation challenges related to neutral wire lengths that needed extensions. Despite these minor drawbacks, the general Consensus leans favorably towards these breakers, with several customers acknowledging that they are a cost-effective solution when compared to alternatives recommended by electrical inspectors. Overall, the dual function breakers have proven to be a reliable choice in enhancing electrical safety in homes, fulfilling a crucial role in protecting circuits near water sources and mitigating potential fire hazards. **Pros and Cons:** **
