Only those who have had big problems, can indeed say that it is useless for big big surge ...
After it is worth checking if one does not exceed the protective capacity of the strip ... especially not plug a washing machine!
The best is an inverter that is clear, with full unbundling at least we keep phone usage, and you can watch TV or listen to music without fear.
This decision protects:
- Protects against surges up to 8 devices (maximum 10A on each outlet)
- Protects the RJ11 ADSL line
- Protects the line from your phone to the ADSL box as part of a fully unbundled
- Protects the arrival of the coaxial external antenna
SURGE PROTECTION TOTAL. BUT NOT IN POWER CUTS!
In the latter case it will study another facility ...
I recommend when the UPS APC RS1500 ...
