3 .0 mounting instructions

Find a safe place and mount the disconnect where it conve-

niently fits, within clear line of sight and less than 50ft / 15m

from the pump. The product should be fixed using appropriate

screws; ensure you have the correct size for the box sizes. The

conduit / cable should be secured and protected against physi-

cal damage. Make sure the installation follows all local codes

and standards.

4 .0 conduit/cables termination

30 amps fused disconnect

The 30 Amp disconnect is provided with 4×25mm-32mm

knockouts (KOs), select the one that will be easiest to con-

nect the cable/conduit. Find the point of attachment for this

KO. Press the edge of a screwdriver against the selected KO's

stamped edge, opposite the point of attachment, and press (or

rap sharply if needed) to push the KO away from the enclosure.

the conduit. Then secure conduit connector into the prepared

enclosure hole using the connector locknut. Then attach the

grounding bushing, having the proper size ground wire lug, over

the connection locknut.

caution

Bonding between the grounding bushing(s) and the

equipment grounding terminal must be included as

part of the installation procedure in accordance with

the local code.

tor either before or after the conduit connector is secured into

the prepared hole using connector locknut
