An overcurrent device (OCD) is the most critical safety feature in your home’s electrical system. It protects the circuit from overload due to excess current and can prevent a possible fire hazard if the inverter doesn’t work correctly. 

An overcurrent device’s function depends on its type, but its primary purpose is to keep the current flowing through the circuit without damaging your modular inverters. 

Overcurrent devices are used in homes and businesses, but they’re also available for industries that use industrial power inverters.

As they prevent the circuit from overloading, they can be fuses or circuit breakers.

There are several types of overcurrent devices: fuses, breakers, trip switches, residual current devices (RCD), and ACSRs (automatic resetting switches) in your home’s Central panel box.

Each type has its unique purpose in protecting your home’s wiring from potentially damaging surges and outages.

Types of devices

The two main types of overcurrent devices are fuses and breakers. 

1. Fuses 

Fuses are inexpensive and available in different sizes. Though you can reset them after tripping, there’s no guarantee they will work the next time again. 

2. Breakers 

Breakers are more expensive than fuses and can be reset if tripped. So, if your breaker trips during a power outage, you won’t have to wait for a technician to come out and repair your electrical system. 

How to install and use these devices?

Since there are a variety of overcurrent devices available, it’s essential to know how to install them. You should also know how to use them and troubleshoot any problems.

Installing an overcurrent device:

  • Ensure you have all your equipment appropriately connected and turn off power at your home’s main service panel or circuit breaker box. 
  • Then ensure all electrical connections are secure and tight. 
  • Use a non-metallic conduit sleeve to guide drilling holes through walls, floors, and ceilings, and insert cables with terminals on each end. 
  • They have plastic tubing with adhesive on one surface, so they adhere well to drywall surfaces without damaging them too much when appropriately installed. 
  • Once the installation is complete, replace any missing screws before turning on the power again to prevent further damage. 

Why do you need overcurrent devices?

Here are some of the reasons why you should use using overcurrent protection devices:

  • They prevent the circuit from becoming overloaded.
  • The overcurrent device will trip and shut off the circuit if a circuit is overloaded to prevent any damage to the device and other things in the circuit.
  • It prevents damage to your electrical system or modular inverters
  • They are essential for safety as they protect against fire and shock by preventing electrical circuits from overloading. Without one, you risk electrocution or injury if your electrical system or industrial power inverters overload. 

Why should you invest in modular inverters with OCDs?

Here are a few reasons why you should invest in modular inverters with the best quality overcurrent devices:

  • Fuses are not as costly and are a cost-effective method to protect your initial investment in batteries and modular inverters. They also protect your equipment and home from accidental fires caused by malfunctioning overloads.
  • Selecting the correct fuse that pairs with your equipment’s output amperage will keep your power system from overheating, prevent internal damage and increase its overall efficiency. 

Thus, overcurrent devices are essential to save your modular inverters from damage and can save you a lot of money in the long run.
