16 current carry conductors
The EMT pipe fill chart provides information on the maximum number of conductors that can be safely installed in a specific size of Electrical Metallic Tubing (EMT) based on the type of conductors and the ambient temperature.
In a three-quarter inch EMT (Electrical Metallic Tubing), the maximum number of 12 AWG THHN conductors allowed is typically 10, according to the National Electrical Code (NEC) guidelines for conduit fill. However, this number can vary based on factors such as the specific application, bundling, and ambient temperature. It’s always important to consult the current NEC code and local regulations for accurate requirements.
According to the 2005 NEC Annex C, table C.1 you are allowed nine #12 THHN conductors in a 1/2" trade size EMT conduit. If your conduit run is any length at all, you would be wise to increase the conduit size to 3/4". as pulling 9 #12's for any length in 1/2" EMT is very difficult.
I haven't been in the EMT field for a few years, but when I was certified the starting salary was around $23,000.
EMT schools teach students everything necessary to become and Emergency Medical Technician. This includes caring for injuries or other emergency health issues such as heart attacks.
Many schools do not list specific prerequisite classes to be taken, however they do require that you have a valid, current CPR certification. This CPR certification will need to be maintained throughout your further schooling and career as am EMT.
It depends on what sort of circuit the resistor(s) is in. The resistor(s) can lower either EMT (Voltage) or Current (Amperage) Sometime resistors are used to create an EMT differential whenever current is flowing.
9 - Is this a test answer or do you just want to know for a project you're doing? Take a look at NEC chapter 9 - tables 4 and 5 (in the 2005 edition at least)
That depends on the size of the conductor and the type, which is defined by its insulation. With many common large feeder conductors such as THHW, the largest conductor which you can run 8 of is # 2 gauge. Whereas common small branch circuit conductors such as # 12 THHN, you can run 138 ea. through a 2 " conduit. For the complete list, look at the chart titled "Maximum number of conductors in electrical metallic tubing" (EMT) in the National Electrical Code.
EMT can earn anywhere from 42000 and 72000 dollars a year. You will need 2 years of basic emt training which can be earned at many universatries.
