Listing and labeling, if it is not listed for a use it is not meant for that use.
I will drop it, you are right to misuse a product and think it will protect you. :fro::fro:
There is a lot of misunderstanding about GFCIs among electricians too I guess is my best answer. I did a 2000 amp service and the NEC says I have to use a GFCI main to protect the service. That does not mean I don't need to GFCI protect outlets in bathrooms etc.
I hear people talk about...
You need a 12 volt source for the LED to light, the diagram that shows the load only light on would be switching a 12 volt control circuit. The 250 volt ratting means you could use the switch to control a 120 or 250 volt load but it is only 5 Amps. The 250 ratting is more to do with being able...
Depends if the dryer wiring was done before of after the 1996 National Electrical code. Before 1996 the ground and neutral wire were combined into one conductor. The 3rd wire being classified as a "current carrying conductor" had to be insulated. This is why you do not see the three wire dryers...
Yes, hot tubs have internal GFCI protection for personal protection.
You said "240v element is immersed in liquid should go without a GFCI?"
If you have a hot water tank and copper pipes you bath in water that is in contact with a 240v element is immersed in liquid every time you take a bath...
What do you need the Disconnect for? That type of GFCI is not designed for personal protection but to protect equipment and will not protect from electric shock. Only 120 volt GFCIs provide personal protection and they even make 120 volt GFCI breakers that are designed to only protect equipment.
The hot liquor tank time does not worry me as much as getting to a boil but I guess I will be starting in the 155 deg F range so I do not have that far to go. I have a 5500 watt element I am going to try with water. My kettle only has on 1" threaded hub so was thinking of just making up a "dip...
Bad idea not to sound rude but that will overheat the windings in your pump and shorten it's life dramatically, a valve is what I use.
They also make controllers for for paddle fans (ceiling fans) that in fact pulse the power on and off to control the speed of the motor.
