Moving 220V to Another Location

Growing up in Texas, I built everything from scratch, wired everything, re-wired large lamps (almost like street lights) in the backyard.

We are looking at possibly getting a new humidifier (I don't know which one just yet) but he said it was 220V. We have a 220 line coming in and it is pretty much right above the furnace / water heater - leads to the dryer (but we use gas).

The quote was $400 but when I pointed out the above, they said maybe $150 - $200. However, how difficult is this really? I can turn the breaker off (way back when) I was working with live wires.

So I really don't see a problem - I cut it, roll it up (for the dryer) and I will have the original ten ft or so of extra installed wire already to install an outlet.

Is there anything I am missing (or am I making it too basic)/

Thank you!

 

It would be 240 not 220. If this is old 3-wire cable for a dryer it can't be used because it has no ground and the unneeded white wire can't by code be remarked as a ground. If it is 4-wire or in continuous metal conduit it can be used. However the breaker size may need to be changed.

 

We would need to know the ampacities of both the new and old circuits.

If the new unit is straight 240 you might be able to use a 2 conductor plus ground cable.

 

What kind of cable is this? Any markings on it? Or is it conduit?
