I think that above you would have to go with a switchboard but in that range where both are available, amps, what about a switchboard would make it prefereable to a panelboard which is less expensive in terms of both space and money?
Location New York, Re: Panelboard vs. Location Wisconsin. Panelboards are wall mounted and switchboards sit on the floor. Switchboards commonly have a main breaker in one section or structure which feeds the rest of the switchboard with a set of horizontal bus. The switchboard commonly is made with panelboard chassis group mounted breakers so if you remove the cover it will look like a bunch of panelboards. However, there are switchboards consisting of individualy mounted molded case breakers that are rear connected.
So as far as whether to use panelboard construction vs. Selecting the appropriate hazardous area panelboard is dependent on:. Hazardous rated panelboards are available with the following NEC hazardous area certifications:.
Panelboards are constructed, and typically shipped, as three separate primary components. To match the construction process, the panelboard cans are typically shipped first, followed by the interiors and the trims. Get your blank panelboard circuit directory template. The branch devices in a panelboard provide overcurrent protection for downstream devices. Most often both functions are provided by a molded case circuit breaker. However, fusible switches can also be provided. Panelboards can be supplied with electronic metering devices to monitor both incoming power to the panel as well as the power distributed through individual branch devices.
These meters can communicate, via common industry protocols, as part of an overall building energy management system. Voltage spikes and surges can find their way into your facility from an outside disturbance or can manifest itself from equipment within your facility.
Surge protection devices SPDs protect sensitive downstream electronic devices from the damaging effects of voltage surges or spikes. Panelboard mounted SPDs can either be side-mounted or integrated design. Side-mounted units come pre-wired in a separate enclosure and are field-mounted and wired to the panel in the field.
In addition to time and space savings, an integrated SPD increases system protection by reducing let-through voltage due to the zero-lead length design. Learn about the many advantages of integrating surge protection inside power distribution equipment. Panelboards, as well as other power distribution assemblies like switchboards and switchgear, carry a short-circuit current rating that defines the amount of fault current that the equipment is designed to withstand.
There are three protection systems used to protect low voltage power distribution systems. They are:. Fully rated protection — where all overcurrent devices are rated for the full prospective short-circuit current at their line side terminals throughout the system. In a fully rated system, the short-circuit current rating of the panelboard is determined by the short-circuit current rating of the lowest rated overcurrent device in the panelboard.
Selectively coordinated protection — A fully rated system where the overcurrent device closest to the fault will open first, thus isolating the faulty circuit. Series rated protection — A short-circuit interrupting rating assigned to a combination of two or more overcurrent protective devices that are connected in series and in which the rating of the downstream device s in the combination is less than the series rating.
Series ratings are also known in the industry as integrated ratings, series combination ratings and series connected ratings. In a series rated system, the overcurrent devices in series in the protective scheme must have been tested and listed by Underwriters Laboratories UL , for series combination use in the system.
