GFCI & ELCI protection has played a major part in reducing the number of victims of electrical accidents, while at the same time protecting expensive equipment. The ShockShield GFCI and ShockShield ELCI protective add-ons are particularly easy to integrate with existing electrical cable runs; depending on your personal preference or the amount of room available at the receptacle, you can either remove the male connector, or insert an In-Line protector. Having these cost effective protective add-ons can help you avoid costly mistakes and protect your personnel.
