Who needs that pesty ground wire anyway?

What is more shocking than the burnt out wire on the left is the yellow and green wire on the right. That wire is the ground wire. It is supposed to be connected to the body of the boiler. It is not. If you look closer you can also see a bolt missing that is meant to hold tight another wire meant to ground the heating element. It is there to protect human life. If G-d forbid there is an electrical leak somewhere the escaping current is meant to run through that wire to the ground. If it is not connected and there is a leak and someone touches that boiler...yup, not good news for whoever touches it...Sadly many boilers we service are not grounded.
