What is a lighting outlet definition?

What is a 4 outlet receptacle called?
Two-duplex outlets are also referred to as quad outlets or four-plug outlets.
What is the maximum distance between receptacles on the same wall?
The maximum spacing between receptacles, according to the National Electric Code (NEC), has been set at 12-feet since 1956–with no point along a wall being more than 6-feet from a receptacle. The logic behind that number is that an appliance with a standard length cord could then be plugged-in anywhere along the wall.

What fan types are affected by Inlet and outlet conditions?
Fan types typically affected by both inlet and outlet conditions are inline fans (both axial and centrifugal) and housed single inlet centrifugal fans. Fan installations with system effects should be avoided if possible. However, in many cases space constraints or other factors prohibit designers to allow for ideal conditions.
How do you calculate outlet velocity on a fan?
Outlet velocity is calculated by divid- ing the CFM by outlet area. RPM Revolutions per minute, the number of rotations the fan shaft makes per minute. SE Static efficiency. Static efficiency is a ratio of the fan power output to the power supplied to the fan.
What happens if there is no discharge duct for a fan?
Without a discharge duct, a system effect will occur. (See figure 12 on page 4 for recommended discharge.) Inline installations are subject to system effect both at the fan inlet and outlet, as shown in Figures 5 and 6. Figure 5 illustrates a poor inlet condition with an elbow directly at the fan inlet.
How do you choose the right duct fan for your ductwork?
For instance, if the duct must turn 90ยบ, a centrifugal fan installed in the turn could be a better choice than an inline fan with an abrupt duct elbow. Select housed centrifugal fans with the proper rotation and best discharge position for the situation.
