Tenpearl Biri-Biri Guard GR-XB Earth Leakage Breaker ②. I used this as a safety device in case of electrical leakage for a small refrigerator while I was extending the ground wire and installing it. The included mounting aid is unused. The instruction manual is included, but the plastic packaging is not. The current price of this product is the lowest price. Please refrain from price reductions.
