Every year, thousands of fires result from surge protectors, power strips and electrical cords. units will trip the breaker if the power strip is over loaded or shorted to prevent overheating.
Q. What is the energy in joules?
Joule, unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 107 ergs, or approximately 0.7377 foot-pounds.

Q. What can 1 Joule of energy do?
One joule equals the work done (or energy expended) by a force of one newton (N) acting over a distance of one meter (m). One newton equals a force that produces an acceleration of one meter per second (s) per second on a one kilogram (kg) mass. Therefore, one joule equals one newton•meter.
Q. Is it bad to sleep next to a surge protector?
No. You probably won’t even notice it but if it’s that close to your face your face you need to move it. There’s no reason for that. I wouldn’t care for it but it’ll probably just go ‘click’ and cut off the power.
Q. Is it bad to charge your phone on an extension cord?
Avoid relying on extension cords when charging devices. Extension cords are not meant for long-term use. If you need to plug in your phone in a more convenient area than is available, this may be an indicator you need more outlets. Don’t make your electronic devices even more complicated than they already are.
Q. Do phones charge slower on extension cords?
An extension cord on the AC input to a charger will have no effect based on the fact that they are designed to run from 100–220V and draw very little current. An extension cord on the output of the charger will probably have some effect based on wire size of the cords.
Q. Are SPDs mandatory?
Simply put; an SPD is required whenever a cable enters or leaves the internal zone (zone 1) from the external zone (zones 0a or 0b). There is also a requirement for additional SPDs to be installed each time a cable or service crosses an internal zonal boundary.
Q. What is a Type 1 surge protection device?
Type 1 surge products are permanently connected devices that are installed before or after a main disconnect. These devices can be used as replacements for what were previously known as secondary surge arrestors or lightning arrestors.
Q. What is a Type 3 surge protector?
Type 3: Receptacle Surge Protector Receptacle surge protectors are inexpensive and easy to install. The most common form factor is a power strip. Not only does this protect a number of devices, but it lets you share a single outlet between many low-power devices.
