Class A puts out ordinary combustible fires (wood, paper, plastic, etc.)
Class B puts out flammable liquid fires (oil, gas, petroleum, etc.)
Class C puts out electrical fires
Class D puts out combustible metal fires (magnesium, titanium, potassium, sodium, etc.)
Class K puts out cooking fires ignited by flammable oil and grease
Since Class A, B, and C fires are all found in conventional homes and businesses, ABC fire extinguishers are designed to put out all three types of fires.
You might come across a fire extinguisher labelled 4A:20B:C. The numbers indicate the size rating of each extinguishing agent. Here's how it works:
The Class A size rating represents the water equivalency. Each number represents 1 ¼ gallons of water. For instance, 2A means the extinguisher is just as effective as 2 ½ gallons of water. 4A is equivalent to 5 gallons of water.
The Class B size rating indicates the square footage the extinguisher can cover. 20B means that as long as you sweep the nozzle side to side, there is enough extinguishing agent inside the canister to provide 20 square feet of coverage.
There is no size rating for Class C. After all, a Class C electrical fire is nothing more than a Class A or Class B fire with energized components requiring a non-conductive extinguishing medium. To effectively fight Class C fires, choose your extinguishers based on the Class A and Class B size ratings.
There is also no size rating for Class D fires. The effectiveness is detailed on the nameplate based on the specific combustible metal for which the extinguisher is recommended.
Now granted, fire and its fumes will do way more damage and be way more dangerous. But if you have the choice between an ABC or a BC for a small grease or engine fire, the BC should absolutely be used. This is why you find BC extinguishers in kitchens, boats, and vehicles where a class A fire is less likely.
I will add one recommendation- keep a box of baking soda under the sink or somewhere nearby the stove. It is always better to dump that on a small grease fire.
A: Dry stuff (wood, paper, etc.)
B: Liquids (oil, gas, grease, etc.)
C: Electrical
The number refers to the size and 5 is smaller than what is usually recommended for home use.

You would want A B C for home use.
There are different requirements for automotive and marine but they overlap a lot - vibration resistance, for example, and the likely types of fires, like a fuel spill. So the same bottle can and does get rated for both.
