Is 300 joules enough for a surge protector?
Anything 300 and under, clamp voltage is good. You would need to add up the wattage used by each item then usually double it to be safe. It depends on how sensitive each of those components are to surges. A surge protector rated for 1,000 joules will protect your devices from surges of 1,000 joules or less.
Can you overload a surge protector?
Multiple outlet power strips (surge protectors, temporary power taps, plug strips, etc.) Multiple power strips must not be “daisy chained” together or used with extension cords. … DO NOT exceed the load (ampacity) rating of the power strip.
Is it safe to put an extension cord in a surge protector?
Can You Plug a Surge Protector Into an Extension Cord? On paper, yes, you can. The biggest thing is making sure the extension cord can handle the same amount of load as the surge protector (or more). … Otherwise, you risk putting too much load on the extension cord and creating a fire hazard for yourself.

Is 200 joules surge protector enough?
Energy absorption/dissipation – This rating, given in joules, tells you how much energy the surge protector can absorb before it fails. A higher number indicates greater protection. Look for a protector that is at least rated at 200 to 400 joules. For better protection, look for a rating of 600 joules or more.
