Breaker Size, Minimum Wire Size | Xantrex Technology HW 1000

Basic Installation Procedures

AC breakers and fuses must be sized to adequately protect the wiring that is installed on the input and output AC circuits of the Freedom HW. All breakers and wiring must be sized and connected in accordance with the electrical codes or regulations applicable to your installation. Table 1-1gives some examples of wiring sizes based on the U.S. National Electrical Code and the Canadian Electrical Code. These examples are based on using a 2-conductor-plus-ground cable rated at 75 °C, and assuming an ambient temperature of up to 30 °C. Ensure that your breakers, and fuses have suitable temperature ratings for your wiring. Other codes and regulations may also be applicable to your installation.

	Breaker Size	15A	20A	30A
	Minimum Wire Size	14AWG	12AWG	10AWG

AC Output	The neutral conductor of the Freedom HW’s AC output circuit (i.e., AC
Neutral	Output Neutral) is automatically connected to the safety ground during
Bonding	inverter operation. When the Freedom HW is using AC shore power, this
	connection is not present, so that the utility neutral (i.e., AC Input
	Neutral) is only connected to utility ground at your source. This conforms
	to National Electrical Code, which requires that separately derived AC
	sources (such as inverters and generators) to have their neutral conductors
	tied to ground in the same way that the neutral conductor from the utility
	is tied to ground in only one place. Check the regulations for your specific
	application to ensure that the installation will comply with the necessary
	requirements. In other words, the AC Input Neutral and Output Neutral
	must be isolated from each other.
DC Cabling	This includes all the cables and connectors between the batteries, the DC
	disconnect and over-current protection device, and the Freedom HW.
	Most mobile installations require multi-strand insulated cables for
	flexibility and durability in high vibration environments and require
	disconnects and over-current devices. Electrical wiring sizes are indicated
	by AWG notation. Under the AWG standard, a larger gauge number
	indicates a smaller wire diameter. Wire size is usually marked on the
	larger sized cables. Table 1-2specifies the minimum recommended DC
	cable size and maximum fuse size for the Freedom HW. The DC cables
	must be copper and must be rated 75 °C minimum. The cables should
	be terminated with lugs that fit the DC stud terminals snugly (8 mm or
	5/16 in. hole size).
