A non-compliant installation due to all the exposed Romex wiring. Romex is a brand name of non-metal sheathing wire.

Can nm wire be exposed?

The National Electrical Code forbids the use of NM cable in situations where it is exposed in a manner where physical damage is possible.

How do you protect exposed electrical wires?

Electrical tape is the simplest method of making electric wires safe. You also use tape on capped live electric wires as an extra precaution. Tapes can be used on loose live wires that do not fit the cap. You can simply use tape over the live wire to fit into the cap.

Is it legal to run Romex in conduit?

When exposed type NM cable is run through a floor it must be protected by at least?





6 inches

If the NM cable is installed where it passes through a floor, the cable must be protected for at least 6 inches above the floor by enclosing it in rigid metal conduit, intermediate metal conduit, or one of the other methods previously mentioned.

Is conduit required for garage wiring?

Many garages contain one or more walls made of concrete or already drywalled. Cable installed on these exposed surfaces has to be protected by conduit. We show EMT (electrical metallic tubing; Photo 7), but you can also use rigid PVC conduit.

Don’t use Electrical Tape to Seal up Loose Wire Ends



Although it may be tempting to keep wrapping new tape around any exposed wires, don’t let the damage get too out of hand. This means anything past a minor abrasion or cut.

Combining metal boxes and PVC conduit is fine, but unlike an all-metal system, PVC requires you to run a separate ground wire and bond it to each metal box or light fixture with either a screw or a special grounding clip.

Why is Romex not allowed in conduit?

This copper wire is what gets exposed if the wire gets damaged, thus leading to other problems. This is why when stripping Romex wires and running them, it is best to use a weather-resistant conduit – especially outdoors or near utility lines.

How do you transition from Romex to conduit?




Quote from Youtube video: Too big we need a reducer stick the reducer on the conduit. Put the wire through the box put the reducer on the other side of the box. Now put your nut on and tighten it up to the conduit.

Can Romex wire get wet?

In most homes, ROMEX® wire is used for electricity, where the copper ground wire is wrapped in paper and then, in turn, wrapped in the live and neutral wires. If this wiring is exposed either through a break in the plastic coating or even at the socket, the moisture can be soaked up by the paper, creating rust.

What type of wire can I run in conduit?

THHN (thermoplastic high heat-resistant nylon-coated) is the best wire for pulling through PVC conduit. Other types of wire have a sticky rubber sheathing that makes them almost impossible to pull.
