Heat tracing can be of 2 types: 1] Electrical Heat tracing: 2] Steam Tracing: Electrical heat tracing can be described as an insulated electrical heating cable, which is spiralled around the process fluid pipe( or object that needs to be heated), after which the pipe and tracing is insulated with the appropriate type and thickness of insulation lagging material. In steam tracing, instead of electrical heating cable, small pile is spiralled which carry steam thereby… Read More
share: Why are electrical cords insulated?
Electrical cords are insulated to prevent the electricity from going from one wire to the other wire without first going through the lightbulb or electrical device. Electricity is lazy. It would rather jump from the hot wire to the neutral wire and go back to the power plant without doing any work than have to go through the light bulb and do some work. You would still have to pay the electric bill. Read More

share: Why can you use electrical devices without getting shocked?
To receive a shock from electrical devices you have to become part of the electrical circuit. Most electrical devices come in two categories. One, the device is grounded and the other is the device is double insulated. The grounded devices have their metallic frames grounded. On a short circuit fault this will trip the breaker and isolate the device’s fault before you have a chance to ground out the device by touching it. The double… Read More

If you have a brand new appliance (hair dryer, toaster, fridge, tv etc) and it comes with a plug with three prongs it has a ground. If it comes with two prongs it is not grounded. The only time an electical appliance should not have three prongs is if it is “double insulated” double insulated means that the electrical components are on a chaisis that is electrically isolated from the outer case or chasis where… Read More
share: What causes an electric motor body to give an electric shock when a person touches it and the ground together?
That condition is called a “ground fault”. That’s when the insulation of the motor winding has a break somewhere, allowing current to leak to the motor housing. The motor SHOULD be grounded, protecting the user from electrical shock, but many older motors were not grounded, providing the potential for just this type of condition. Newer motors are often “double insulated”, meaning that not only is the motor winding insulated, the motor housing is also insulated… Read More

share: Is a fuse a device that keeps electrical circuits from over heating?
A fuse is a device used to keep electrical circuits from overheating is not a true statement. A fuse is used to protect the wire of the circuit from an over current being applied to the circuit. This over current could be caused by a couple of scenarios. Two non insulated conductors touching one another and creating a short circuit. Another cause could be an non insulated conductor touching adjacent grounded equipment. Whatever the cause… Read More
