Example 10-1 – HPWH Ready:

Question:

I am installing a propane water heater in a garage and the designated future HPWH location is in the same space, do I need to install a dedicated 125V, 20 amp electrical plug connected to a 3-conductor 10 AWG wire?

Answer:

Yes. Most modern efficient gas water heaters require 125V, 20 amp power to operate. The electric ready requirement is designed to easily convert the installed 120V electrical circuit to 240V, capable of powering a HPWH. If the installed gas water heater does not have an electrical connection, a dedicated 240V, 30 amp circuit can be provided at the designated HPWH location, along with dedicated space in the main panel for a double pole breaker.

Example 10-2 – HPWH Ready:

Question:

I am installing a split-system HPWH. The storage tank is in an interior closet and is separate from the compressor and evaporator, which is located outside, do I need to meet the electric ready requirements for water heating?

Answer:

No. If a HPWH is being installed, either split-system or integrated, the electric ready requirements do not apply. They only apply when a gas water heater is being installed.

Example 10-3 – HPWH Ready:

Question:

I am installing a 120V HPWH, do I need to meet the electric ready requirements for water heating?

Answer:

No. If a HPWH is being installed, regardless of the voltage, the electric ready requirements do not apply. They only apply when a gas water heater is being installed.

Example 10-4 – Electric Cooktop Ready:

Question:

If I am installing a gas range, do I need to meet the electric ready requirements for cooktops?

Answer:

Yes. Because your range includes a gas cooktop, the electric ready requirements need to be met.

Example 10-5 – Electric Clothes Dryer Ready:

Question:

If I am providing both gas piping and a dedicated electrical circuit for the potential for either a gas or electric dryer to be installed by the homeowner, do I need to meet the electric ready requirements at the dryer location?

Answer:

If you are installing a dedicated 240V, 30 amp or greater plug for an electric dryer, in addition to a gas stub-out for a gas dryer, you are meeting the electric ready requirements for clothes dryer.
