However, interconnecting these devices is a violation of Occupational Safety and Health Administration (OSHA) regulations and the National Electrical Code because doing so can cause them to become overloaded, which could lead to their failure and a possible fire.
Second, you'll simply run out of outlets eventually, and although you might think you can daisy change an additional surge protector for more outlets, you're wrong. Whether it's a surge protector or a basic power strip, you should never daisy-chain them for a couple reasons.
Power strips are not meant to be used in conjunction with another power strip. In fact, plugging multiple power strips together, which is known as “daisy-chaining,” violates most fire safety codes and can quickly overload your electrical system. For the same reason, avoid the use of extension cords with power strips.
With low-quality sockets on inferior extensions, the sockets themselves can become faulty. A circuit overloads and ultimately, an electrical fire can be created due to the amps exceeding the capability of the components to handle it.
The shortage of outlets and abundance of devices often makes daisy chaining seem like an effective solution to power woes, but the risk of blowing fuses or starting an electrical fire can be high. Overloading and short circuiting are common in daisy chain setups.
However, interconnecting these devices is a violation of Occupational Safety and Health Administration (OSHA) regulations and the National Electrical Code because doing so can cause them to become overloaded, which could lead to their failure and a possible fire.
How many power strips can be safely chained together?
You can connect an infinite number of power strips together to power low-wattage devices, like cell phone chargers, without any problems. It is only a fire hazard if the current (amperage) of the power strip is exceeded, like when plugging in a space heater.
How many power boards can you safely daisy chain together?
Never plug a power board into another power board
If your power boards don't reach quite far enough or you need some extra plugs, it's tempting to string multiple boards together, daisy-chaining them by plugging one into the next. In a word – don't. It can cause one or more of the boards to fail or even catch fire.
When you piggyback one surge protector onto another, you're creating hazardous electrical issues. These safety devices aren't designed to plug into one another.
Is it OK to plug 2 surge protectors in one outlet?
Yes, it is safe to use two surge protectors at once on the same outlet. However, it is not safe to power heavy electricity consuming devices, such as heaters, air conditioners, refrigerators, etc. Overloading a surge protector is bad and can cause costly damage, including fire.
For an extension cord to be considered as being used in its intended application, and therefore NRTL-approved, the employer must follow all marked warnings and limitations associated with that cord, including a warning contained on a tag affixed to the cord that provides, "Do not plug one extension cord into another." ...
See reference information. Power Strips & Surge-Suppression devices: Must have overcurrent protection (circuit breaker). They are required to plug directly into a permanent wall or plug mold outlet. Do NOT plug them into each other or piggyback them.
Even if there are six sockets in your power strip, you should only use one or two at a given time. Plugging multiple power strips into one wall receptacle. You should never have more than one outlet per wall receptacle serving a power strip.
Like all daisies, these are only made to be progress capture devices for aid climbing and should never be used as an anchor or as PPE as their buckles will not hold more than body weight.
We don't recommend using daisy chain power supplies. Ground loops are commonly caused when using a daisy chain power cable to power multiple pedals. This creates a ground loop between every pedal in the daisy chain. Ground loops allow stray magnetic fields to introduce hum into your signal path.
The advantages of daisy-chaining include a reduction in cable clutter when using multiple displays as you reduce the number of cables connected to the system, it is cheaper in terms of construction and it extends the range of displays from the system.
The piggyback method is when you essentially overload a power board by plugging one plug in and then connecting it to another to create a longer cord. Piggy backing is also a term that is used when you use a double adaptor to turn a single outlet into a double outlet.
The National Electrical Code (NEC) does not limit the number of outlets per circuit. The NEC only states that a circuit cannot supply more than 80% of the circuit breakers limits. This is so the circuit breaker does not constantly trip during regular use. As many as you want—as long as you don't plug the first one in.
OSHA's electrical safety rule at 29 CFR 1910.303(b)(2) allows the use of power strips as long as they are installed and used in accordance with instructions from the manufacturer and included in the listing or labeling on the device from a certified source such as UL (Underwriters Laboratory).
An electrical daisy chain is formed when power strips and surge protectors are connected using other power strips or extension cords. This violates both NEC and OSHA regulations, as this often leads to electrical failure or fire.
Those not covered by the OSH Act include: self-employed workers, immediate family members of farm employers, and workers whose hazards are regulated by another federal agency (for example, the Mine Safety and Health Administration, the Department of Energy, Federal Aviation Administration, or Coast Guard).
Do not plug power strips or other surge protectors into one surge protector and ensure the devices you have plugged in do not exceed the wattage capacity. An overloaded protector fails to stop a power surge that can ruin your electronics or even cause fires.
Is it OK to plug a surge protector into another surge protector?
You should only use one surge protector or power strip at a time in a single outlet. Plugging multiple strips and protectors into each other at once is a fire hazard. Not to mention, it would defeat the purpose of the surge protector, and could overload your electrical system, causing symptoms like flickering.
