If the breaker box has a main switch, the breaker controlling the hot water heater will be on the side of the box opposite the main switch. If the box does not have a main switch, look for a breaker that is larger than the others; this is typically the breaker for the hot water heater.
4 Steps to Tell Which Breaker Is For Hot Water Heater
If your hot water heater is electric, you can find the breaker by tracing the wires from the heater back to the breaker box. The breaker will be labeled with the word “water” or “heater.” If your hot water heater is gas, the breaker is usually located near the furnace.
One of the most important skills that a homeowner can learn is how to tell which breaker is for their hot water heater. This knowledge can be incredibly useful in the event of a power outage, as it can help to prevent any unnecessary damage to the appliance. Additionally, if there is ever a need to reset the breaker, knowing which one controls the hot water heater can save a significant amount of time.
Step 1: There Are Usually Labels On The Breakers That Indicate What They Power
There are usually labels on the breakers that indicate what they power. To find the breaker for the hot water heater, look for a label that says “hot water heater” or something similar. If there is no label, try flipping all the breakers until the hot water heater turns off.
Step 2: The Breaker For The Hot Water Heater Will Be Near The Water Heater
The breaker for the hot water heater is usually near the water heater itself, or it may be labeled as such. If it is not labeled, you can usually find it by following the wire from the water heater to the breaker box.
Step 3: The Breaker Will Be A Certain Size, Most Likely Either 15 Or 20 Amps
To determine which breaker is for the hot water heater, first identify the breaker box and locate the breakers labeled “hot water heater” or “HWH.” If there are two breakers labeled “HWH,” the larger one is most likely the 15-amp breaker, and the smaller one is most likely the 20-amp breaker. If only one breaker is labeled “HWH,” it is most likely the 15-amp breaker.
Step 4: If There Is No Label On The Breaker, You Can Test To See If It Is Hot By Flipping It Off And On Again
If there is no label on the breaker, you can test to see if it is hot by flipping it off and on again. If the breaker is hot, it will be labeled “HOT.”
