2. carry electrical current from the source to the load or current consuming
apparatus;
3. hold and secure wires to its fixtures inside and outside houses and buildings.
4. protect houses, buildings, appliances, and instruments from destruction and
damage.
The following are the most commonly used electrical materials.
COMMON WIRE SPLICES AND JOINTS
As a student in Electrical Installation and Maintenance, you should acquire
the important knowledge and skills in wire splices and joints and be familiar with
the actual application of every splice and joint. This will serve as your tool in
performing actual wiring installation.
The following are common electrical wire splices and joints.
Rat Tail or Pig Tail
This kind of joint is commonly used to join
two or more conductors inside the junction
box. It is suitable for service where there is no
mechanical stress when wires are to be
connected in an outlet box, switch, or conduit
fitting.
Y-splice
This method of wrapping is generally used on
small cables because the strands are flexible
and can all be wrapped in one operation.
Knotted tap
This is used where the tap
wire is under heavy tensile stress.
Plain tap joint
This is used where the tap wire is under
considerable tensile stress circuit.
Aerial tap
This is used as a temporary tap usually done
in constructions sites. The easy twist will
facilitate tap wire movement
Duplex cross joint
This is a two-tap wire turned simultaneously
and is used where the two tap wire is under
heavy tensile stress.
Western Union Short-tie Splice
This is the most widely used splice or joint in
interior wiring installation to extend the length
of wire from one point to another
Western Union Long Tie
This is used extensively for outside wiring to
extend the length of wire from one end to
another.
Cross joint
The same application is done
as in plain tap but the only difference is that
this tap is a combination of two plain taps
placed side by side with each other.
Wrapped Tap or Tee Joint
This is used on large solid conductors where it
is difficult to wrap the heavy tap wire around
the main wire.
EXTENSION CORD
An extension cord is a span of flexible electrical power cable with a plug on one end and
multiple sockets on the other end. It comes in several varieties to suit the needs of the user.
One of the most important considerations is the power handling capacity to make it safe
and functional.
Electrical gadgets are product of modern technology to make our life better. The
number of electrical gadgets available at home and in offices may exceed the existing
convenience outlet installed in every room. The best remedy to address the insufficiency of
available outlet is to use an extension cord especially if the electrical gadgets need to
operate at the same time

DIFFERENT TYPES OF FORMS
Correctness of the entries in different forms used in electrical work is necessary in
order to acquire right, complete, and accurate number of materials and tools needed
for a specific electrical job. Here are samples of different forms used in electrical
work.
1. Purchase requisition is a document generated by a user department or
storeroom personnel to notify the purchasing department about items it needs
to order, their quantity, and the time frame. It may also contain the
authorization to proceed with the purchase. This is also called purchase
request or requisition. Below is the sample of Purchase Requisition Form.
2. Inventory are raw materials, work-in-process goods, and completely
finished goods that are considered to be the portion of a business's
assets that are ready or will be ready for sale. Inventory represents one
of the most important assets that most businesses possess, because
the turnover of inventory represents one of the primary sources of
revenue generation and subsequent earnings for the company's
shareholders/owners.
Below is the example of the Inventory of Materials Form.
3. Job Order or Work Order Form is a written instruction to perform a
task according to specified requirements, time frame, and cost
estimates
4. Borrower’s Form is a form used to request for tools and equipment
needed for a particular job. It indicates the department the borrower is
connected, with the date, the job that is to be done, the person who will
approve the request, when it was returned, and if it was in good
condition. Sample of the borrower’s form is located below.
Receive and Inspect Electrical Supplies, Materials and Tools
One of the tasks of a supply officer or logistics officer is the purchase of the
company’s supplies, materials, and anything that the company needs. But this duty
does not end in just purchasing but also in receiving the deliveries of what was
purchased. In receiving the deliveries, understand that you need to ensure that the
right materials and supplies were delivered and all are in good condition without
defects.
A. When you receive a shipment, ask the shipper the following
questions:
1. Is it for me? Check the delivery receipt for the consignee's name and address.
If your agency has more than one location, make sure the goods are for this
exact address. Check the freight to see if it is the same as what is described
on the delivery receipt. Look at the label on each item to make sure the
shipment belongs to you.
2. Is it damaged? Do not sign the receipt before inspecting for damage. Check
for holes, water, stains, and tears. Pick up cartons if you can. Check for
rattling. Listen for something broken inside. Check to see if any package has
been opened or if the sealing tape has been tampered with.
3. Is the piece count correct? Count the pieces and match the number on the
delivery receipt to the number you have counted. If the shipment is on a pallet,
check to make sure the pallet is solid with no voids inside the stack. If the
shipment is shrink or stretch wrapped, make sure the wrap hasn't been cut
and pieces removed. Sign only for the type of unit you receive. For example:
two pallets. Don't sign for the number of packages that are supposed to be on
the pallet. However, if time permits or the pallet is not banded or shrink
wrapped, count the packages, and only then sign for the number of packages.
B. If your delivery doesn't check out, do one of the following:
1. Refuse shipment if it isn't yours, if the shipment does not meet the terms
specified by your agency, or is damaged to the point where it no longer has a
value.
2. If yours, and only partially damaged or short, accept it and note exceptions on
the delivery receipt.
C. How to note exceptions:
1. Damage Notations: Be specific. Describe the damage accurately. Pinpoint the
locations of all defects. If you can see the damage, have the driver wait while
you open and inspect the packages. Write down the number and identity of
the
damaged pieces. This is called a "joint inventory.
2. Shortage Notations: If part of shipment is missing, write the number of pieces
actually delivered on the delivery receipt and circle it. Then write down the
number of pieces missing and note them as "short."
3. Signatures: Write down all exceptions on both copies of the delivery receipt.
Have the driver sign both copies of the delivery receipt in his full name (not
initials or nicknames). After the driver signs, you sign also. Write your agency's
name, you full name, the date, and the time of day.
D. Follow these steps when requesting an inspection:
1.The receiving person is responsible for requesting the carrier to inspect the
damaged goods and packaging. The formal request should be made by phone right
after discovering any loss or damage.
2. After the phone request, make a request for inspection by the carrier in writing.
Note the date and time of your previous phone call and the person contacted. Keep
a copy of your request letter on file.
3. Once contacted about damage or shortage, the carrier may waive inspection and
tell you so. If so, write down the name of the person who waived the inspection, and
the date and time of waiver. Then conduct your own detailed inspection. Write up
your findings in a report and attach it to the file. If you can, take photographs to
confirm your inspection report.
