Can I plug a new dryer into an old 3-prong outlet?

Not to code and not safe long-term. Modern dryers ship with 4-prong cords; either convert the outlet to 4-prong (correct) or the dryer cord to 3-prong (only allowed in some grandfathered situations).

Why did the code change from 3-prong to 4-prong?

3-prong dryer outlets used neutral as ground — if the neutral broke, the appliance chassis became energized. 4-prong separates neutral and ground for safety.

How much does dryer outlet installation cost?

Existing circuit conversion (3→4 prong): $175–$300. New circuit from panel: $400–$800 depending on distance.

Can I add a dryer circuit to my basement laundry?

Yes. It's a common install — we route from the panel to the new location with minimal drywall damage.

Do gas dryers need a 240V outlet?

No — gas dryers use a standard 120V outlet for the motor and controls. Only electric dryers need 240V.

What amperage is a dryer circuit?

30A 240V. Never share with other appliances.

Can you install a stackable washer/dryer combo?

Yes. Combo units may require different outlet configurations — we verify with the model manual.

What if my panel is full?

We add a tandem breaker or small subpanel — details depend on panel model and load calc.

Do I need a permit for a new dryer outlet?

Yes in every DMV jurisdiction for a new circuit; sometimes not for a like-for-like outlet swap.

How long does the installation take?

Outlet conversion: 1 hour. New circuit: 3–5 hours depending on wire run distance.
