21 Mar Stapled Wires and Arc Fault Breakers and Why We Need Them
Lets talk stapled wires, why is it code to staple wires and what happens when the staple goes through the wire?
Cables are typically secured with cable staples or with stacker devices that secure multiple cables in one location. There are a few important rules to follow when choosing and installing staples and other cable fasteners:
- Use the proper size of fastener for the size and number of cables being secured.
- Use insulated staples and fasteners. Avoid plain metal staples, and never use standard staples or other fasteners that are not designed for electrical installations.
- Position cables flat against framing before securing them; do not fasten cables on-edge.
- Secure cables snugly but not so tightly that the cable is damaged or indented from the fastener.
- Use stacker-type fasteners to secure multiple cables to the same framing member. These allow the cables to be stacked for a neater, safer installation. The clips are either nailed or screwed to the framing, and the cables are secured by clipping them into the slots.
- Avoid sharp bends in the cable immediately after a box, a drilled hole, or a staple or clip. Cables must not be bent in a radius smaller than 5 times the cable diameter.
Arc Fault Breakers, why do we need them?
Arc Fault Circuit Interrupters or also known as AFCI, is a circuit breaker that is designed to sense an arc, which is an electrical “leak” often caused by damaged or deteriorating wires and cords that can cause a fire.
Now don’t forget about GFCI or also known as Ground Fault Circuit Interrupters which monitors the electricity flowing in a circuit. This device reduces the risk of electrical shock by shutting off the electric power circuit when it detects that current is flowing an unintended path, such as water or a person.
So basically you need these breakers to live in a safe environment.
