A contractor friend of mine performed the following experiment and asked for my explanation this evening.
A 5 gal plastic bucket is filled with water. electrical cord (with insulation stripped from the ends) is placed into the water in the bucket. The lamp cord plug is then placed into a GFCI receptacle. Circuit is in a house that is easily 60-70 years old. My friend tells me the GFCI did NOT trip and the breaker did NOT trip and he wants to know why not.
Soooo what is the explanation ??
Here is my response. The circuit could be ungrounded, 2 conductor wire based on the age of the house. The GFCI didn’t trip because current is NOT unbalanced between the two lamp cord leads. The breaker didn’t trip because even though the water is a good conductor the leads had to have been far enough apart (I have no idea how far apart) that the electrical current could not overcome the resistance of the water.
And now the million dollar question…If I place my hand in the bucket should the GFCI trip?:shock:
