Quality of Electrical Wiring and Service
Wiring should be up to current NEC standards and have verified good
AC grounds. It is important that your computer system be plugged into
a grounded AC outlet when charging and that all peripherals connected
to your system reference the same AC ground.
Selecting the Right Equipment
There are a number of companies that sell quality surge suppressors
such as Sutton Designs, APC, and Panamax. When you are looking for a
surge suppressor, consider these things.
•
Expect to pay at least $50 for a good quality surge suppressor.
•
The surge suppressor should be a UL 1449, 497, and 1283 listed
for surge suppression, modem surge protection, and RFI/EMI noise
filtering respectively.
•
The surge suppressor should have diagnostic LEDs that verify good
AC ground, proper wiring, and proper surge operation. Lighted on/off
switches are not recommended since they can produce electrical
noise.
•
The Joule ratings should be a minimum of 480 Joules for the AC
surge circuit.
•
The Joule ratings should be a minimum of 240 Joules for the
modem.
•
The modem surge circuit should present low capacitance to the
modem line or it will slow the transmission rate. Capacitance should
be specified at less than 50 picofarads.
•
Quality surge suppressor manufacturers generally offer a lifetime
warranty.
•
Consider obtaining a protected equipment coverage policy which
insures the equipment in the event of surge damage.
•
The devices that will be attached to the computer also need to be
surge protected.
