Electric dryer cable run

I need to get power to my electric dryer- There is a 220Volt dryer outlet next to it- it runs up to the attic (where all most of my electrical connections are)- It just ends in the attic since renovations were done. I need to extend it another 75 to the electrical panel in the garage- Can I just join the old cable with a new one in a metal junction box? I have done this before with 110- Is it the same for 220?

Yes.... you can splice/extend the cables in a junction box with a cover.
The existing wiring should be #10 for a 30A dryer receptacle. The cable you add should also be #10.

The first question to answer before extending the cable is whether or not it is 4 wires or three. A three wire circuit should not be extended.
