It depends upon local code, but for Colorado, I found this document:
http://www.dora.state.co.us/electrical/forms/HomeownerPermits.pdf
It says:
The main service equipment / panel shall be mounted either outside or inside the dwelling as near as possible to the point of entrance of the service conductors to the building. All service equipment and electrical panels shall have a clear area 30" wide and 36" deep in front of the equipment. This clear area must extend from the floor to ceiling with no intrusions from other equipment, cabinets, counters, appliances, pipes, etc. Service equipment/panels are not allowed in a clothes closet or bathroom.
I thought I had read that the panel should be at centered least 36" above the floor, but can't find that. Basically I think the idea is that the panel be high enough that most people can easily look at it and used from a standing position. I'll update this answer further, if I find out more information.
Thanks,
Andrew
code is a minimum of 4' and max of 6' from floor to main disconnect breaker
I believe the NEC states that the panel must not be more than 6' from the floor.
The main stars of the film Breaker Morant would be Edward Woodward and Jack Thompson. The film Breaker Morant was released in the year 1980 in Australia.
I imagine you are talking about an actual fuse box, as opposed to a breaker box. These are different. One has circular fuses, the other has breakers, which generally look like switches. If it is a fuse box, unscrew the circular fuse and replace it with a fuse of the same amperage. The amperage is noted somewhere on the top of the fuse facing you when you look at in the fuse box. It will either be 15A [A for Amps] or 20A if it is in a house. If it is a breaker, and it is just tripped, turn it all the way off, and switch it back on. If the breaker is actually bad, use should call an electrician.
outdoor main gate entrance height
42 inches from ground to bottom of the mail box.
Standard is 48" to the top of the switch box.
The amperage capacity of the main bus bars and the connection of the main breaker to the bus bars.
Breaker boxes do not have fuses associated with them unless the main disconnect is independent from the breaker box. If that is the case both fuses have to be the same in the main disconnect that protects the breaker box.
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.
Its not recommended because your new main breaker will allow up to 100 amps and your old wire can only safely handle 60amps. If you put a 60amp main breaker in the new box, that would be acceptable. No, it is perfectly safe. Because the box is overrated, there is no problem. If the box is the main panel, and not a subpanel, install a 60A main breaker so you cannot overload your service. If it is a subpanel this 60A breaker should be in the main panel.
the problem is between these two breakers or you have a faulty or oversized breaker closest to the spa.
Yes
No. Power to all the circuit breakers will be cut off except for the Main power breaker. The Main power breaker (which supplies power to all other breakers and will say 100, or whatever your max breaker box power is, on it )will have power going to it all the time, unless power is turned off outside the house.
The wiring is like this:[[30KW Motor ---- Star Delt Starter(100A Breaker inside) ----- 200A Breaker------50A Breaker(Inside the breaker box which located inside the factory) -----100A Main Breaker]]Once I try to start the Motor, the Main Breaker trips immediately.
You can reduce the breaker size because that limits the current that can reach the main panel. There is no safety issue other than the significant danger in an unskilled person changing out a main breaker.
Yes. You'll seldom run every circuit to full capacity. The main breaker will trip if all the individual circuits exceed the 200 amp rating of the main breaker.
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
A sub-panel is always fed from a main panel. The main panel is situated where the electrical service wiring first enters the main structure on a dwelling plot or building site.A sub-panel can be situated within the same building as the main panel or it can be in a subsidiary building or structure (such as a garage, garden shed or workshop) that is separate from the main building.More informationA sub-panel is another name for a secondary breaker box, just as "the main panel" is another name for "the main breaker-box"."Breaker-box" and/or "panel" are just alternative short names that are used instead of the full name "circuit breaker box".
