Surge Protectors

Been told by the guys at the electric shop that I need to check the joules on the surge protector and that the higher the joules the higher the protection.. True?

surge arresters clamp at different voltages .some 275v some 600volt some virtually never unless a huge shunt .your incoming supply should have a permanent surge arrestor usually by Surgetek across mains .live and neutral and a pigtail to earth .heineman makes one that takes up a circuit breaker opening .all for different applications but they are not fool proof spikes still get through so individual protection is also recommended as well as sensitive stuff on a standalone small ups and a delay on fridges.gate motors and electric fences are very susceptible to static discharge from a lightning strike that cant be stopped easily .i wont install anything other than Surgetek .also bear in mind if your earth leakage suddenly starts tripping one of your small plug in units may be faulty .possibly after a shunt .

Thanks for the info.

I do have a few Ellie's surge protector plugs and multi plugs. Think I'll use that as an extra layer of protection then for the more "expensive" electronics.

Just get the

Clearline Tripconnect 1P and protect your entire setup and not just one device. Fully programmable and does over and under voltage. The ellies is one or the other.​

Ideas to protect large Kyocera copiers?

We thinking 3000va UPS or Mecer Inverter + Battery?

Do your homework here, I speak under correction but there's a lot of current draw at startup/warmup. We were never allowed to connect them to UPS or building dedicated red plugs, same with large laser printers.
 
becarefull of what you install .a lot of units are only load limiters (to prevent the guy in the granny flat from haveng a bake off every night)with no surge arrester only impulse current and voltage control may work for basics but not sure about spikes ,there you need MoV s inside and even gas arrestors to clamp the spike efficiently

also speak to your insurance .some only accept say Surgetek and give you special rates .especially if installing in db .the good ones you can also replace the mov pack .

Quick question.. So now that the fridge safe plug is in,should I carry on switching off the DB board when we have LS.. I normally switch it on 10 minutes after power returns(when it's during the day)
