Electrical Engineer Portable Handbook

1.0 INTRODUCTION

This chapter provides information of a general nature that is frequently needed by the electrical design professional. Information that follows in subsequent chapters is more specific and closely follows the design process.

1.1 CHECKLISTS

The following checklists should prove useful in the execution of projects.

1.2 ELECTRICAL SYMBOLS AND MOUNTING HEIGHTS

Electrical Symbols

Electrical symbols can vary widely, but the following closely adhere to industry standards. Industry standard symbols are often modified to meet client and/or project specific requirements.

Mounting Heights

Mounting heights of electrical devices are influenced by and must be closely coordinated with the architectural design. However, there are industry standard practices followed by architects as well as code and legal requirements, such as Americans with Disabilities Act (ADA) guidelines. The following recommended mounting heights for electrical devices provide a good guideline in the absence of any specific information and are ADA compliant.
