A conduit run is installed from the ER to a TR. It has two (2) 90 degree bend and a length of 20 m (65 ft). What will be the MINIMUM test rating of the pull cord left in the conduit?

20 kg (44 lb) is insufficient for a conduit run with two 90-degree bends - this low rating applies only to very short, straight conduit runs.

40 kg (88 lb) does not meet the minimum rating required when two 90-degree bends are present, as bend friction multiplies the required pull tension.

60 kg (132 lb) is below the BICSI-specified minimum threshold for conduit configurations containing multiple 90-degree bends.

Per BICSI TDMM, a conduit run containing two 90-degree bends requires a minimum pull cord test rating of 90 kg (200 lb). The cumulative friction added by each 90-degree bend significantly increases pulling tension, and the standard mandates this higher rating to prevent cord failure during cable installation.

100 kg (220 lb) exceeds the minimum required rating - while it would function, the question asks for the minimum, which is 90 kg (200 lb).
