Build Your Own Current Limiter for Protection when Repairing and Testing Electronic Equipment

This video describes, in detail, how to construct a Current Limiting Device to protect you, your test equipment, and any electronic gear that you are testing or repairing. When used properly, it prevents short circuits from causing additional damage, particularly to expensive power transformers in amplifiers. It is also quite useful when first powering up previously untested and vintage equipment. It is not suitable for use with medium to large electric motors. The bulb functions as a high-wattage resistor
