Why would only one side of a 240V water heater line blow fuses periodically when elements and voltages test OK?
=== === == == (LIFE SAFETY WARNING! [disclaimer] Electricity is dangerous!
You can be injured or killed!
Improper installations can cause fire, injury and death!
Why would the same FUSE [important] keep blowing when conductors and voltage seem ok?
Troubleshooting is the final measure of skill and knowledge!
It is the knowledge of how electricity works, and of the methods and materials used to create a functional wiring system, that enables a skilled troubleshooter to locate the problem and repair it.
Where should the "voltage" be, and how does it get there?
And where shouldn't it be?
I see two possible causes of your problem ...
1] There is a very high current draw, caused by an intermittent fault to ground in one conductor at some as yet undiscovered point.
2] There is some heat source causing the FUSE [a melting thermal device] to open when there is normal current because there is not enough differential remaining between the fuse's ambient temperature and the melting point of the fusible element [loose fitting fuseholder, loose screw connection, loose conductor termination, and so on ...]. ... or, of course, the installation was done by a hack and there is another load somewhere you haven't recognized ...
== == <><><> Replace the elements, they are inexpensive, next check the wiring to ground. Those are the things a homeowner can do. If there is still a problem call a Pro. == == <><><> Thanks, Robert. Looking closer, I found that one of the fuse holders in the disconnect box was totally shot. I am surprised I did not have a fire. Replaced the old disconnect with a new one using breakers. Everything fine now. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What is a ephiphyseal line?
Epiphyseal line is the junction between diaphysis (long part of the bone) and epiphysis (growing end of the bone). This is the region where the growth of bone takes place. Gradually as an individual approaches puberty, the epiphysis fuses with the bone and the growth stops.
What does the dm stand for on horn and dm fuse?
In the context of electrical fuses, "DM" typically stands for "Double Module." This designation indicates that the fuse is designed to fit in a double-width space within a fuse holder or distribution board. The term is often used in relation to specific fuse types, such as those used in industrial or commercial electrical systems.
Change positive ground to negative old tractor?
---------------- You really don't need to replace anything! But his will allow you to ADD the more common negative ground accessories. This will work for tractors, trucks, cars... whatever. Switch the wires at the coil. Reverse your battery connections (turn your battery around and connect positive cable to positive post on the battery) and connect the negative cable to the ground. Connect a wire from the positive post of the battery. Take the other end of the wire and brush it against the "F" (field) post on the voltage regulator until you see a few sparks. DO NOT CONNECT THIS END, just brush it a couple times. Check all your fuses. Reverse the wires on your gauges or the display will be backwards.
How many watts does a ge fcm7suww 7 cubic foot freezer use?
The specification plate on that GE model freezer says 120 Volts at 1.7 Amps running. So 120V x 1.7A = 204 Watts running. But remember, electrical motors typlically draw about three times the running current when they first start and spin up to speed. So the starting current would be about 1.7A x 3 ~ 5.1 Amps when starting. This is important if you have fuses - be sure to use a Slow-Blow fuse (10 or 15 Amp). If you have circuit breakers then a 15 Amp breaker should be fine. And if you need and extension cord be sure to use one reated at least 15 Amps. - The VillageElder

Why does a electric unit blow fuses periodically during the winter heating season?
This could be due to an overload on the circuit caused by additional heating demands during cold weather, resulting in blown fuses. You may need to upgrade your electrical system or redistribute the load to prevent this issue from recurring. Additionally, inspect for any faulty wiring or connections that could be contributing to the problem.
