Are gould type qp breakers compatible with square d?

Gould Type QP circuit breakers are not compatible with Square D panels, as they are designed for different specifications and standards. Gould breakers typically fit into specific Gould panel designs, while Square D breakers are made for their own panels. Mixing these brands can lead to safety hazards and malfunctioning breakers. Always use the correct brand and type of breaker specified for your electrical panel to ensure safety and compliance.
