What the function of panelboard?
An electrical panel board is a place wherein power generation can be monitored. This is also wherein the generated power is distributed.
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..
Could a Variable Frequency Drive be installed inside the Main Distribution Board for electrical works?
A VFD could be installed in a MCC (Motor Control Center) but not in a main distribution panelboard. There is not enough physical room in a distribution board once it is full of breakers. To change any physical aspect of the panelboard will void the UL/CSA rating of the panelboard. As for using the MCC the VFD can be installed in any bucket module. MCC units can be factory manufactured to have the VFD pre-installed.

Why it is important to properly ground your electrical appliances?
The ground wire is the low impedance and direct return path to the distribution panelboard. The ground wire carries any fault current back to the panelboard. This fault current is what trips the circuits protection. This protection can be either a fuse but more likely an electrical circuit breaker.One common mistake in the electrical trade is the thought that the ground wire connects to the neutral bus or wire. The ground wire does not connect to the neutral wire or the panelboards isolated neutral bus.The ground wire connects to the ground bus in the panelboard. This is an non-isolated bus that is threaded directly to the panelboard enclosure. The only place the ground bus and the neutral connect to each other is through the neutral bonding screw. This is a screw that goes through the neutral bus and threads itself into the enclosure of the panelboard thereby picking up the ground bus.

What type of panel should be used in 3 phase 400 amp?
The type would be a three phase panelboard. If you are carrying the wye neutral into the service, then it would be a three phase four wire distribution panelboard. Regardless of the style used, it would have to have a minimum 400 amp bus.
