Product Features

- The Surge protective devices(SPDs), suitable for residential,commercial and industrial appications, are designed to limit transient overvoltage and run-off lightning currents.

- It provides reliable protection from the destructive effects of lightning and switching



- are lightning current arrsters, they can handle and divert high energy from lightning.

-they are necessary when the installation is exposed to direct lightning(for example when the buiding is equipped with external lightning protection system or powered by aerial lines).

Do you work on location video or film shoots? Do you, sometimes, blow out breakers in the breaker box because you put too many tungsten lights on one circuit? This will cause you to lose precious time. This tutorial is very short but has the answer. Learn how to perform simple electrical math calculations in amperes (amps) so you can determine quickly whether or not you are about to overload a circuit with lighting. It’s so simple. Most lights are rated in watts. So, amps=watts/voltage. That means that if you have a 1000 watt light on a circuit in a house, and the house power is 110 volts (American voltage) then the calculation would be 1000/110= 9.09, which rounds up to 9.1 amps. So, that light uses 9.1 amps. You want to know amps because household circuits are rated in amps. So, if you had two 1000 watt lights plugged into one wall plug in a house, it would be 9.1 times 2 which equals 18.2 amps. Most household circuit breakers in American homes are 15 amp breakers. That means that you have 18.2 amps of lights plugged into a 15 amp breaker. That breaker will trip. You’ll lose time because you will have to find the breaker box, find the correct breaker, reset it and try something else.
The way around this problem is to bring extension cords and run them down the hall to other rooms and run lights from plugs that are in other rooms. This will help get your lights hooked to other circuit breakers.
