A suitable disconnect device must be provided as part of the building installation. The purpose of the
disconnect device is to provide an easy and accessible means for removing power from the product for
servicing.
A suitable branch circuit protection device must be provided as part of the building installation. The purpose
of branch circuit protection is to limit current in the case of a fault.
The disconnect device may also provide branch circuit protection (for example, a circuit breaker). Alternately,
separate disconnect and branch circuit protection devices (fuses and a disconnect switch) may be employed.
The devices must be rated based on the plate rating of the product in accordance with the applicable local
codes and specific customer requirements. Branch circuit protection is commonly selected based on 125% of
the product input rating. Such derating is to avoid nuisance tripping due to load surges or power transients
and to meet code requirements. Applicable codes and customer requirements will vary.
