Electricians suggest that the wire must be secured after every 6 feet with the final fastener being no more than 12 inches away from the fixture. The NEC is rather strict about Romex wire and has several regulations specific to Romex conductors.

Is there any disadvantage in using exposed wiring?

The risk of fire is present because the cable is in open conditions. Exposed to weather to be affected by humidity, rain, smoke, sunlight, oil, vapor, steam, etc. this wiring system is not long-lasting. After some of the duration, sag is produced in the cables.

What is the difference between conduit wiring and surface wiring?

In one method conduit is laid on the surface of the wall, ceiling etc. This is called surface wiring. The other method is to lay the conduit recessed in wall or ceiling, and this system is known as concealed wiring. Conduit may be rigid or flexible.

What are the 4 types of conduit?

Electrical Conduit Types

  • Rigid Metal Conduit (RMC)
  • Electrical Metallic Tubing (EMT)
  • Intermediate Metal Conduit (IMC)
  • Flexible Metal Conduit (FMC)

Does outdoor electrical wire need to be in conduit?



Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.
