1 Function

This document allows framework manufacturers to offer frames ahead of having familiarity with the particular electric hinge being utilized.

2 Scope

retard dating site

The information included herein relates to frames stated in accordance with ANSI A250.8. The planning as defined herein will accommodate nearly all electric hinges sold. It is the responsibility of this hardware specifier to assure hinges that are compatible utilized.

4 Tolerances

All values that do not carry certain tolerances or are perhaps not marked maximum or minimum shall have the following tolerances Linear proportions shall be В± 1/16 in. (1.6 mm). Weight or force shall be В± 2%. Angles shall be В± 2 levels. Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option associated with the https://datingmentor.org/political-dating/ manufacturers.

5 Location

The preparation for electric hinges will be non-load bearing. In order that it shall be found in the center hinge preparation on structures with 1-1/2 pair of hinges, and on the second hinge from the underside on frames with 2 pair of hinges.

6 Hinge Reinforcement

The hinge reinforcement shall conform to ANSI A250.6 and ANSI A250.8, and shall incorporate cutouts as shown in numbers 1, 2, 3 and 4.

7 Junction Box

A junction field can be provided to facilitate wiring and connector installation. In addition, a gap will probably be supplied at the top and bottom associated with junction box to enhance conduit (see Figure 4). It’s the responsibility for the electrical contractor to connect any unused holes.
