Product Information

The wiring is reversed– The main issue here is the Live (brown) and the Neutral (Blue) wires are wired incorrectly; they should be opposite to what they are. These feature one or more blades that are inserted into a plug, making them easy to remove and reinsert. Then use the following as a guide to select the correct fuse:3 Amp fuse for appliances up to 700 Watts,5 Amp fuse for appliances ranging from 700 to 1000 Watts,13 Amp fuse for appliances over 1000 Watts.

This is because halogen lights draw a significant surge of current at switch on as their cold resistance is far lower than their resistance at operating temperature. Then turn the cable grip back to its normal position, and put the screw back in place; tightening both to secure the flexible cable in place. For example on 500 W halogen floodlights it is normal to use a 5 A fuse even though a 3 A would carry the normal operating current. Voltage drop is the voltage lost through cables due to impedance - essentially when the voltage at the end of a run of cable is lower than at the beginning. Have your fuse box assessed by a professional electrician and be prepared to replace it if necessary.Reproduction in whole or in part in any form or medium without express written permission of DIYnot Limited is prohibited.

The 182651-1 from TE Connectivity is a CPC series circular I/O plug connector housing with shell size 11 and suitable for 4 pin contacts.

I am happy to be proved wrong but it is my understanding that the fuse rating was to ensure that the cable did not take more current than it was capable of and thus presented a potential fire risk.

Until that earth pin is pushed in the live and neutral don’t have connection to their terminals, meaning by this point the earth (safety) grounding is already connected, making it safe for the user, so if they accidentally touch the other pins, they will be protected by the earth connection and the insulation.

Generally these days, most new, domestic appliances come with a pre-fitted moulded plug that already incorporates either a 3Amp or 13Amp rated fuse. Whilst it is handy to know how to wire a plug it’s not something you’re going to need to worry about if you use us for your portable appliance testing, as we’ll do it for you.
