FAQ
What is the SP240V185KA mainly used for?
The SP240V185KA is commonly used as a high-capacity Type 2 whole-house surge protector for residential, light commercial, garage, workshop, and small business 120/240V split-phase electrical systems.
Where is the SP240V185KA installed?
The SP240V185KA is typically installed inside the electrical panel or electrical enclosure and connected through a compatible 20 amp double-pole circuit breaker. Installation should be performed by a qualified electrician or licensed contractor.
Is the SP240V185KA a Type 1 or Type 2 surge protector?
The SP240V185KA is a Type 2 surge protective device. Unlike many other Bad Wolf whole-house surge protectors, this model is designed for Type 2 installation only.
Does the SP240V185KA need to be installed with a circuit breaker?
Yes. The SP240V185KA must be installed with a 20 amp double-pole circuit breaker in accordance with the product instructions and applicable electrical codes.
Can the SP240V185KA be installed without a circuit breaker?
No. The SP240V185KA is a Type 2 surge protective device and must be connected to a 20 amp double-pole circuit breaker. It should not be installed as a Type 1 SPD without a circuit breaker.
What type of electrical system is this surge protector designed for?
The SP240V185KA is designed for compatible 120/240V split-phase electrical systems commonly used in homes, garages, workshops, small businesses, and light commercial applications.
Can the SP240V185KA be used as a whole-house surge protector?
Yes. The SP240V185KA can be used as a whole-house surge protector when properly installed as a Type 2 SPD on a compatible 120/240V split-phase electrical system.
What does the 185KA rating mean?
The 185KA rating refers to the surge current capacity of the device. It is designed to help protect connected electrical equipment from damaging surge events when properly installed on a compatible system.
Does the SP240V185KA protect against lightning?
The SP240V185KA is designed to help protect against surge events caused by indirect lightning activity. No surge protector can guarantee protection from a direct lightning strike, but a properly installed surge protective device can help reduce the risk of damage from surge energy entering the electrical system.
Does the SP240V185KA provide EMP, CME, or solar flare protection?
Yes. The SP240V185KA is designed to help protect against damaging surge activity associated with electromagnetic disturbance events, including EMP, CME, and solar flare related electrical disturbances. Proper installation, grounding, and bonding are important for effective protection.
What does the green status light mean?
The SP240V185KA has a single green status light. When the green light is on, the surge protector is functioning correctly. If the green light is off, the surge protector needs to be replaced.
Does the SP240V185KA have a red indicator light?
No. The SP240V185KA does not use a red indicator light. It uses a single green status light to show whether the surge protector is functioning correctly.
What is the remote display unit used for?
The remote display unit allows the SP240V185KA to be installed inside the electrical panel or enclosure while still providing a visible status light in a clean, professional location. Using an extension cable, the remote display unit can be flush mounted into drywall or another suitable material.
How does the remote display unit work?
The remote display unit has a single green status light that works the same way as the green light on the surge protector. When the green light is on, the surge protector is functioning correctly. If the green light is off, the surge protector needs to be replaced.
Is the remote display unit required?
The remote display unit is used when the installer wants a cleaner finished look or when the surge protector is installed inside an enclosure where the main status light may not be easily visible.
Can this surge protector be installed outdoors?
No. The SP240V185KA should only be installed indoors and in a suitable electrical enclosure or panel location. Always verify the installation environment, enclosure requirements, and applicable electrical codes before installation.
