Yes, standard Cutler-Hammer electrical panels are generally considered very safe and reliable. Unlike notorious historical failures such as Federal Pacific Electric Stab-Lok or Zinsco panels, Cutler-Hammer panels (particularly the Type CH line featuring copper bus bars) were built to high engineering standards. However, any electrical panel that is several decades old should be inspected periodically by a licensed professional to check for loose terminal connections, thermal wear, or environmental corrosion.
