2 AMP FUSE SERIES
The KLDR Series fuses closely match most control power transformer characteristics, which permits them to be sized in accordance with the latest revisions of UL 508 (Industrial Control) and UL 845 (Motor Control Centers). These small-sized fuses provide excellent protection of motor branch circuits containing IEC or NEMA-rated motor controllers or contactors. KLDR Series time-delay fuses are designed to protect control transformers, solenoids, and similar inductive components with high-magnetizing currents during the first half-cycle.

(Note: sub-panels don't always have main breakers they may have lugs only, which allow the feeder wires to be connected.) Because the subpanel is fed by the main panel, you do not add the subpanel's amp rating to the household total use the main panel's amperage only.Littelfuse products are not designed for, and shall not be used for, any purpose (including, without limitation, automotive, military, aerospace, medical, life-saving, life-sustaining or nuclear facility applications, devices intended for surgical implant into the body, or any other application in which the failure or lack of desired operation of the product may result in personal injury, death, or property damage) other than those expressly set forth in applicable Littelfuse product documentation. If your home has a subpanel, there will be a double-pole breaker in the main panel that has the same amp rating as the main breaker in the subpanel. 60-amp fuse panel: Installed from 1950 to about 1965, 60-amp fuse panels provide 240 volts of power but are still insufficient for most homes. Such a service provides insufficient power for modern usage and generally needs to be updated. They have their own main breaker, which is fed by the main panel. 30-amp fuse panel: Installed before 1950, these service panels provide only 120-volt current. Subpanels are typically 60 to 100 amps and often have branch circuits serving a specific area of the house, such as a kitchen. A subpanel can also serve as a convenient satellite panel for a detached garage or workshop that may be far away from the main panel. Subpanels are commonly installed to accommodate the many new circuits and breakers added as part of a home addition or large remodel. If you have a 400 amp service, you will have two 200 amp main panels and each will have a 200 amp main breaker.Īn electrical subpanel is a secondary service panel that is fed by the home's main service panel. The amp rating on this main circuit breaker identifies your electrical service size. Turning this main breaker to the off position shuts off power to the entire house and all the branch circuits.

It is a double-pole breaker, connected to both 120-volt service wires to power both hot bus bars running down through the panel. The main circuit breaker dictates how much power is available to your entire house.

The main circuit breaker may be bolted in place, or it may be a snap-in breaker similar to those serving branch circuits.

In rare instances, the main circuit breaker may be mounted at the bottom of the service panel. This is the main circuit breaker, and its amperage rating will be something like 60, 100, 150, or 200 amps.

The amperage of these individual breakers will be between 15 and 50 amps, usually.Īt the top or bottom end of the two rows of branch circuit breakers, there will be a central circuit breaker that controls the power to the entire panel. These individual, or branch, circuit breakers are numbered, and they control individual branch circuits running through your home. Inside the panel, you will see two rows of individual circuit breakers with small toggle levers. Make sure the floor near the main service panel is dry, then open the metal door on the service panel.
