Many people are unsure about the size surge suppressor to purchase – a 7.5 amp, 15 amp or 20 amp model?

Home Office/Computer
Most computer systems draw less than 5 amps so a 7.5 amp suppressor would do the job for a typical computer set-up. If you have a lot of “extras” that are sharing the suppressor or need to protect 2-3 computer systems with one suppressor, a 15 amp model would be required. To insure you are choosing the right size, calculate the amps required (see below).

Home Audio
For a typical audio set up, 15 amps would be fine. If you have specialty items with a 20 amp plug or are plugging many “extra” high load accessories into the unit, a 20 amp model would be needed (which requires a 20 amp wall receptacle and wiring). To insure you are choosing the right size, calculate the amps required (see below).

Home Theater
For a simple TV with a VCR and/or DVD, look at the 7.5 amp model. A TV and sound system would require additional capacity so look at the 15 amp models. If the TV and sound system have many “extra” high load accessories or 20 amp receptacle requirements, you would need a 20 amp model (which requires a 20 amp wall receptacle and wiring). To insure you are choosing the right size, calculate the amps required (see below).

Using Product Information to Calculate the Amps Required
You can consult your product manual or equipment label for load information. If it lists the watts but not the amps, a simple calculation can be performed. To calculate from watts to amps, divide the total watts by 120 (600 watts = 5 amps). Do this for all of the equipment you would like to protect, total them, and you will have your minimum size requirement.
