Junction box labeling is required by Code (NEC) on boxes containing fire alarm circuits and circuits fed from emergency power panels backed up by generators. However, it is a good trade practice to always label your j-box covers with the circuit voltage and circuit numbers.

Can I use a junction box as a pull box also?

Yes, a junction box can be used as a pull box, provided it meets the necessary size and code requirements for pulling wire. The National Electrical Code (NEC) specifies that a box must be large enough to allow for the bending of conductors and to prevent damage during installation. Ensure that the junction box is accessible and properly rated for the application to maintain safety and compliance.

Is it necessary to ground at all metal junction boxes when using metal conduit or cable?

In a completely metallic conduit system it is not necessary to ground each junction box as long as the metallic system has the grounding capacity rating larger than that of the over current device protecting the circuit. The code book states what size conduits are rated at, for grounding amperages.


Why are you only allowed 360 degrees of bend jn a electrcal condit run?

Any more than four 90 degree bents (equaling up to 360 degrees) or a combination of other bends will make it quite difficult to pull the wires into that pipe. This is why the electrical code prohibits more than 360 degrees. If you have to put more bends than that, place a junction box on the line after the first 360 degrees. This way you pull to the junction box and then use that junction box so continue the rest of the way.
