Receptacle Location

[wireday]

I am installing a receptacle for equipment that requires 240 Volt, The location for the receptacle is right beside a 208 Volt panel that is recessed into the wall, I will be fishing down the wall to 240 receptacle beside 208 Volt panel, Everything will be labeled, Is it OK

So how are you getting 240v? or does the equipment work with 208V

 

[Dennis Alwon]

If you are meaning that you have a 240v circuit and it is wired near a 208v panel then that is not an issue

No they need the 240 for heat equipment, the 240V is located away from this area, but will be beside the 208 panel,

That is not a problem at all.

It would be nice to label the receptacle with the panel ID and CB #, so the next guy doesn’t waste time looking.

If you going to wire 240 volt rated equipment on to 208 that is usually OK although you will get less output. Check the name plate and the MFG info.

But maybe I am not clear on what you are doing.

Will there be a step up transformer to boost 208 to 240 volts?

Also how do many of you handle horizontal fire block studs when fishing cable through vertical drywall?

The block I’m referring to is the wood 2x4 laid horizontally between normal wall studs. Usually to penetrate through this block I find the horizontal fire block with a stud finder and cut the drywall in a small square above and below this block in order to drill a hole through this fire stop using a 90 degree paddle bit adapter and save the drywall piece for patch up. Is there another easy to do this and where in NEC does it allow such nm cable to be ran in walls without being supported and secure for installs with pre-existing drywall?

Yes, and yes.

You can usually use a flex-bit to drill through fire-stop blocking, and pull the wire with it.

Sometimes blank cover is acceptable

 

[LarryFine]

Sometimes blank cover is acceptable

Agreed. I have used LV rings and blank plates as hole covers many times.

I like the way the bit is almost centered..
Mine generally drilled right on the edge of the plate.

I have learned they are easy to center when you have access on the other side of the wall.

Try the aiming handle, or a ball.

 

[Little Bill]

I have managed to hit the edge/corner even using the ball. What I try to do is find the opposing wall, then bend the bit to find the wall near you, then try to just scoot it enough to try for the center. I try to push down so the stinger catches and doesn't scoot, then start the drill slow until I'm sure it is feeding through.
Still, it's a crap shoot sometimes.

Yea, when it wiggles the baseboard you're not sure if that's a win or not.

Depends on what's below.

Lots of depends with those things. I call them the gamble bit: you feeling lucky, punk?
