Answer:
The "J" stands for joule and is a unit of work or energy. The higher a j rating on a surge protector the more energy absorption/dissipation it can handle before the device fails.
The higher the j value the higher the level of protection and thus the more expensive it is. For some lights or low end kitchen appliances … see more

The higher the j value the higher the level of protection and thus the more expensive it is. For some lights or low end kitchen appliances 200-400j will be fine. 600 joules or more are better for things like a thousand dollar TV or PC stuff (clamp voltage and response time are also good to have). Hope that helps. see less

Answer:
No, It's wired for 110 volt system, you can buy 240 volt surge protector, they make several different types, you can also have one put into your electric panel box to protect your whole home, they have several different styles of these also.

Answer:
Actually, the joule rating for surge protection, has nothing to do with how many watts your load wattage is. It is a rating of how much excess energy a given device can absorb during sudden surges in voltage. For anything electronic that cost more than a few hundred dollars, I would recommend 2,000 joules or higher. … see more Actually, the joule rating for surge protection, has nothing to do with how many watts your load wattage is. It is a rating of how much excess energy a given device can absorb during sudden surges in voltage. For anything electronic that cost more than a few hundred dollars, I would recommend 2,000 joules or higher. Remember, the joule rating is actually 3 times what is actually afforded across any two-leg pairs. So, if the rating is 3,000 joules, there is actually only 1,000 joules across any given wire pair, such as hot to neutral, or neutral to ground, or hot to ground.

Remember, surge protectors also protect themselves, so the higher the joule rating the better! see less

Keep in mind not to overload your 15 amp circuit by filling the outlets. If I did attach it to the wall use a screw type with an attached backing fastener by drilling a small hole in the wall and feeding it through then tightening the screw. That will grasp the inside of the wall and then you can slip the outlet device to it. see less Personally, I would not mount it with a permanent attachment and would mount with good double faced tape.
