What is main function of distribution bars?
Distribution bars allow a vehicle to pull more weight without damaging the rear axle or interfering with steering. They function by adding some leverage to both sides of the hitch, which allows for more even distribution of the load's weight.

Is normal distribution also a probability distribution?
Yes. When we refer to the normal distribution, we are referring to a probability distribution. When we specify the equation of a continuous distribution, such as the normal distribution, we refer to the equation as a probability density function.

What is radial distribution system?
There are 3 type of power distribution namely loop,network and radial.Radial distribution is the type of power distribution where the power is delivered from the main branch to sub-branches then it split out from the sub-branches again. it is the cheapest but least reliable network configuration.

Does a sub panel need a main breaker?
Answer for Canada, USA and countries running a 60 Hz, 120/240 volt, split supply service.The main distribution panelboard has to have a main disconnect. This has been in the electrical regulations since the late 50's.If the sub panel is in the same home under the same roof line, the sub panel enclosure does not need a main disconnect because it is just another branch circuit. Connecting a sub panel to a separate free standing garage or workshop is a different scenario and is governed by a different set of electrical code regulations.What needs to be done to the panelboard is physically remove the neutral bonding screw. This is the screw that bonds the panelboard enclosure to the neutral bus. By doing this it stops a secondary ground pathway for a fault current from the sub panelboard to flow back to the main panelboard on the sub panel's neutral feeder.The electrical code requires that there is only one position on an electrical distribution service where the distribution enclosure and the neutral bus join each other. That is at the main disconnect of the first over current device, which is the main service disconnect breaker or a fused disconnect switch whichever your system uses..
