Kitchen wall cabinets are usually hung 18″ above countertops, 54″ above floor and 24″ above the stove. In an accessible kitchen, cabinets can be hung at 15″ inches above countertops.
Customer ServiceCommon standards in the battery room include those from American Society of Testing Materials (ASTM) and Institute of Electrical and Electronic Engineers (IEEE). Model codes are standards developed by committees with the intent to be adopted by states and local jurisdictions.
Stationary storage battery systems shall be located and constructed in accordance with this section. Stationary storage battery systems shall be housed in a noncombustible, locked cabinet or other enclosure to prevent access by unauthorized personnel unless located in a separate equipment room accessible only to authorized personnel.
Battery cabinets shall be provided with exterior labels that identify the manufacturer and model number of the system and electrical rating (i.e., voltage and current) of the contained battery system. Signs shall be provided within battery cabinets to indicate the relevant electrical, chemical, and fire hazard.
Batteries housed in enclosures are notorious for having poor access. The writer has seen examples of enclosures, which are over 1m deep with less that 50mm between the top of cells and the underside of the shelf above.
In layman's terms, a standard provides minimum requirements and/or instructions in agreement within the industry for common reference. Common standards in the battery room include those from American Society of Testing Materials (ASTM) and Institute of Electrical and Electronic Engineers (IEEE).
It is worth remembering that a battery cannot be isolated in the conventional way and will always be live, even when fully discharged. It only takes a few milliamperes to kill a person. Stands that are two rows deep are generally easy to service but those of three or four or more rows deep may be difficult to service.
