Electric Tankless Water Heater Facts
How can I make sure there is no security problem with my water heater electric tankless?
Over electrical issue. I have a new electric tankless water heater I installed. Be tankless, it uses a lot of power (6 AWG breaker 70 amps single phase 220). I've Got It AC adapter via a cable disconnect near the radiator because of the thickness cable. Everything is going well and I'm sure I wired correctly. Yet with all that power I just want to be sure about the facts concerning electrocution danger with this configuration. I have the ground wire connected properly. Not sure if this matters, but the ground wire is very close (perhaps even touch the case) to the son in the disconnect. I have plastic PVC plumbing in the house. Given this configuration, is there a danger that I may never be electrocuted if this device was a short circuit or a malfunction or if the ground wire never touched One of the hot wires? Then the water in a plastic pipe, even do this kind of power? Thank you for any information!
First, making available high power no longer gives rise to the electrocution of only 15 amps, because it takes only a fraction of an amp travel through a human body to cause death. The 220 volts, however, is more than enough energy to drive a mortal of current through the dry skin of man (The first line of the body of your defense) – and therefore the configuration of your merit caution and respect. Regarding the ground touching a son hot yes there is a danger if a bare portion of the son of contact. The danger, however, is not so much as is the electric fire. If one touches of hot lead on the ground without proper insulation, you will have a direct cost. The circuit breaker can save you, but the pipe can get very hot very quickly and damage isolation, perhaps in a place that you can not see. Also note: the tension between an energized conductor and the ground is 110, but the tension between the two hot leads is 220. The answer to your question is that as long as the insulation is well made and put in place so that it can not touch them through ", and your tank is grounded, you're probably quite safe. And yes, assuming that your water is a mineral in it, water in a 1 / 2 "plastic pipe can certainly exert enough power to be dangerous.
